I’ve got a bunch of wireless mics and a single “backup” mic. I figure that since individual channels (as opposed to sockets) can’t really go bad on a dLive, instead of allocating a fader to the backup mic on my surface, I’d set the B input on the relevant channels to be the backup mic. The problem is that I don’t really have enough softkeys to have a “Set A” and a “Set B” softkey for every channel. It’d be handy if you could set a softkey to either toggle between two of the ABCD sockets, or cycle through the sockets which are assigned (like, I think people would probably want to skip from B to D if C wasn’t assigned). The softkeys already have RGB LEDs for backlighting, so you could assign a different color for the A, B, C, and D sockets to make it easy to tell at a glance which socket is active.
