PLS HELP: Mapping Question Driving me Crazy

PLS HELP: Mapping Question Driving me Crazy

Hello all,

Let me quickly tell you about my setup:
External 4 channel mixer
1 X1
1 F1

X1 is controlling decks A&B
F1 is controlling deck C with remix sets

What I would like to do is to control deck C without losing much functionality on either X1 or F1 for simple looping etc.

Can someone please help me get this to work? I’ve been searching like crazy but couldn’t find a way to just switch the controlled decks on X1!

Thanks in advance and hope everyone is staying safe!

Can you please explain this in greater detail??
