Editing output channel assignments in the group editor

Hi,
I use Mixosaurus drums via Kontakt, and occasionally need to re-route its channel outputs, due to refining my workflow.

I have been labouriously opening up each kit piece's (kick, snare, hats etc) "group editor" and left clicking each kit piece's individual components/mic's in order to "group" them, then re-assigning them in a way which is more convenient (for my purposes). IOW, close mic's to a "close mic" output channel, OH's to an "OH" output channel, rooms to rooms, PZM to PZM etc etc.......

My question:
Is it possible to achieve this same result with (something like) a doc file? Left clicking (and hoping I don't screw up with those tiny little boxes) a bunch of individual sample/components is not exactly brain surgery, but it is labourious.

Cheers,
Bob.
