is it possible to edit the xcrtl mode or mappig or what ever, hahaha of the x touch to controll the x air in the way i want it?

and if yes how?

if no is there a work around?

reason is the missing implementation of the controlls to the polarity switch and the stereo link on the x touch. for me only via x air edit app possible.
but i dont want to have a controller for a mixer to not have accsess to all parameters damn B*******, but the controller its self i like it, cause of the amount of faders n knobs for that price and the posiblity to controll my DAW but i realy need the controlls of my mixer too.
