Midimix changing Pan to a 3rd Send

I want to remap the Pan knob to a 3rd Send.  I started to make this change but do I also need to setup maps for ALL of the other controls, even though I’m not overriding their behavior?

I tried simply remapping the Pan Knob in Ableton, and it works fine.  But it doesn’t move with the Bank Left/Right functions.

Thx
