Change screen in wentward

In my opinion that screen looks absolutely terrible and too simplistic to fit my taste. Any way I can change it?
The thing I want to change is the white background to an image.

Is it possible or is it not able to be changed at all?

 

I think it is not possible to do that but you can change the Route Name and the Route Number!
A Youtube Tutorial here:
That also display in the Bus!

 

use this code
controller.onGameplayEvent("bus_onRouteChange", {direction="NORTE-PORTINO", routeID="3"})

 

Late response my bad,
I'm looking to change the background, I know how to change the route number.
The white background is my problem, but if its impossible to change, guess I cannot do anything about it.
