S212 NTG 4.7 program physical AUX button

[ro-76]

I have a 2014 s212 with NTG 4.7. I've installed an apple carplay box which works great. I use the stock system for radio only and the carplay setup uses AUX for audio. I would like to program the Navi or Disc button to switch to AUX if possible. This would allow me to switch from radio to carplay without going into the menu. Is this possible in the engineering menu? Thanks

Nope.
