Unsolved Variable References

I built my own mod for my Automation imports which will allow me to add a CVT to my Automation cars without modifying the imported file in any way. The CVT is very customizable in the game so that I can tune it to each car which requires me to have quite a few variables.

What I'd like to do is to display a variable as text in the Tuning menu.
Here is an example of my code for another part of my mod:

Code:

        "variables": [
            ["name", "type", "unit", "category", "default", "min", "max", "title", "description"]
            ["$multi0", "range", ":1", "Booster", 1, 0.1, 4, "Multiplier @ Low RPM", "Multiply the torque values of the engine by this number."{"stepDis":0.05, "subCategory":"Multipliers"}]
            ["$multi1", "range", ":1", "Booster", 1, 0.1, 4, "Multiplier @ Mid 1 RPM", "Multiply the torque values of the engine by this number."{"stepDis":0.05, "subCategory":"Multipliers"}]
            ["$multi2", "range", ":1", "Booster", 1, 0.1, 4, "Multiplier @ Mid 2 RPM", "Multiply the torque values of the engine by this number."{"stepDis":0.05, "subCategory":"Multipliers"}]
            ["$multi3", "range", ":1", "Booster", 1, 0.1, 4, "Multiplier @ Hi RPM", "Multiply the torque values of the engine by this number."{"stepDis":0.05, "subCategory":"Multipliers"}]
            ["$RPM0", "range", "rpm", "Booster", 0, 0, 3000, "Low RPM Range", "Rpm range to apply to hi engine torque multiplier."{"stepDis":100, "subCategory":"Ranges"}]
            ["$RPM1", "range", "rpm", "Booster", 3000, 3000, 5000, "Mid 1 RPM Range", "Rpm range to apply to mid engine torque multiplier."{"stepDis":100, "subCategory":"Ranges"}]
            ["$RPM2", "range", "rpm", "Booster", 7000, 5000, 8000, "mid 2 RPM Range", "Rpm range to apply to hi engine torque multiplier."{"stepDis":100, "subCategory":"Ranges"}]
            ["$RPM3", "range", "rpm", "Booster", 12000, 8000, 12000, "Hi RPM Range", "Rpm range to apply to hi engine torque multiplier."{"stepDis":100, "subCategory":"Ranges"}]
        ]
        "mainEngine": {
            "torqueModMult":[
                ["rpm", "torque"],
                ["$RPM0", "$multi0"],
                ["$RPM1", "$multi1"],          
                ["$RPM2", "$multi2"],          
                ["$RPM3", "$multi3"],

In this part of the code I would like to display the value for "$RPM0" in the first line of the code where it says "Multiplier @ Low RPM". Ex: if "$RPM0" = 1000 then the line should read "Multiplier @ 1000 RPM".

Is there any way of doing this?
