I’m sure you could swap panels and boards to make the sport button a button. However, if the ecu doesn’t know what to do with the input, it won’t go far. Similar to adding cruise control, you’d have to make the ecu recognize the button for it to work.
The question is if that’s something you can activate or deactivate with TechCenter. Im not sure, so hopefully someone with more knowledge can answer that question.
Sourcing the buttons would be the first step after finding if you can program the ecu, don’t know how pricy those things are.
