Activating channel for the VDINs

Hi Gustav 

I am currently working on a project where the operators must wear gloves. Since making any touch interactions would require gloves to be off I implemented side J1939 bezel keys. What would be super helpful is if the VDINs could have an activating channel added such that if the side button is pressed, touch button would respond accordingly. 

No sure if there any any way this can be done now.
