hi
yes that would be awesome! A current work-around is limited; use [SEND] block to Sendout > FOH or AMP. You'll lose the use of MAINout and a BLOCK but now you can receive FOH mix to Stomp AUXin, control vol, IEM with headphone out. It would great help if they add this, especially those of us with 'silent stages', sequence or clip tracks, 'pit' work, etc.
I (and a few others) have posted this on L6 Ideascale:
