mhhh... you are talking either using the Group Faders (1/2,3/4) for the selected channels (Desk Group out - Effekt- Desk Return)

or the desks have a feature called "swap" or "flip". On my soundcraft gb4 i am able to use the 4 Groupfaders as aux sends 1-4.

All the Best

Russ Disciple recently shared on Facebook two videos of himself dubbing. He seems to be doing just what you described.
On his digital desk he is switching the left hand faders to different functions several times during each take.
