Reply to 4-Deck Traktor Pro w/ Herc Steel

First i apologize for yet another thread about this but ive searched for a while and cant find anything that addresses this specifically

Anyway, has anyone successfully mapped a button (for ex. the stop button) to switch Deck A to Deck C and B to D? Ive been trying several things for a few hours and my last idea is maybe to remap the midi controller itself, so that the stop buttons act like the shift buttons, but i cant figure out how to do this exactly.

Any help would be greatly appreciated, even if its saying to just return this for an rmx, as from what ive read i believe that might be much easier. thanks!
