Setting two differential modes in one mode

I am working on a transfer case that can lock and unlock the front and rear differentials in the different drive modes, such as locking both diffs in 4lo and unlocking them in 2hi. It would be simple enough using stock open/locked diffs, but I also added lsd/locking diffs. This would also be simple, but I want to be able to control either one without creating multiple parts (no control f/r, open/lock f no rear, etc...) Ideally I could set diff_f/diff_r to open and lsd at the same time. I have tried

Code:

            "2hi": {
                "name": "2WD High Gear",
                "order": 10,
                "settings": [
                    ["type"]
                    ["powertrainDeviceMode", {"deviceName":"lowrange", "mode":"high"}]
                    ["powertrainDeviceMode", {"deviceName":"transfercase_F", "mode":"disconnected"}]
                    ["powertrainDeviceMode", {"deviceName":"differential_F", "mode":"open"}]
                    ["powertrainDeviceMode", {"deviceName":"differential_F", "mode":"lsd"}]
                ],
            },

as well as

Code:

 ["powertrainDeviceMode", {"deviceName":"differential_F", "mode":"lsd"}] 
["powertrainDeviceMode", {"deviceName":"differential_F", "mode":"open"}]

and

Code:

["powertrainDeviceMode", {"deviceName":"differential_F", "mode":"lsd", "mode":"open"}]

but it will only set whichever line comes second. so "mode":"lsd" ... "mode":"open" only sets an open diff but leaves an lsd locked.

I have also tried

Code:

["powertrainDeviceMode", {"deviceName":"differential_F", "mode":"lsd","open"}]

Code:

["powertrainDeviceMode", {"deviceName":"differential_F", "mode":"lsd":"open"}]

Code:

["powertrainDeviceMode", {"deviceName":"differential_F", "mode":"lsd" "open"}]

but these all throw an error and stop the game from reading the part properly.

Trying

Spoiler

Code:

["powertrainDeviceMode", {"deviceName":"differential_F", "mode":"lsd"}, {"deviceName":"differential_F", "mode":"open"}]

causes the game to crash any time it tries to load the file.

I could use diff toggle instead but I want it to set the diff mode each time you enter a 4wd mode so that locking/unlocking a diff independently won't throw off the whole system. The ability to turn off the auto locking per axle would be nice as well.

I tried making a slot

                ],
            },
        }
    }

,

and

Code:

 "controller": [
        ["fileName"],
        ["driveModes", {"name":"transfercaseControl"}]
        ["4wd", {"driveModesTransfercaseNames":["transfercaseControl"], "driveModesRangeNames":["transfercaseControl"], "driveModesDifferentialNames":["driveModesDifferentials"]}]
    ],
    
...
    
"differential_F_controller_LSD": {
    "information":{
       "name":"LSD Front Differential Controller",    },
    "slotType" : "differential_F_controller",
    "driveModesDifferentials":{    

but it wont switch the slot to the different modes.

I can override "transfercaseControl" in the slot but that just moves the problem of making a part for every combination of front and rear no control, lsd control, and open control to the slots instead of the main transfercase, as well as having to dive into the engine>transmission<transfercase>slot every time you want t change a diff type. . My idea from the beginning was to simplify the whole process and make it dummy proof, but that just trades the complexity from operating it to setting it up,

 

One solution might be to use the "Components" function to store variables from the diffs and apply them to the transfer case modes.

Put this in the diff Jbeam

"components": {
"frontDiffType": "lsd"
},

Then do this to apply it to the transfercase.

["powertrainDeviceMode", {"deviceName":"differential_F", "mode":$=$components.frontDiffType}]
