Reply to Map footswitch to come out of loops?

I've been using the footswitch on the S4 for the loop recorder, which I use on rare occasion. I was wondering if I could remap the switch to come out of loops (in the main decks). Basically if I start one or two loops in the main deck, and I'm messing around with filters/delay/reverb/etc, I don't have the free hand to kick the track back out of the loop. I'd love to be able to make the footswitch do this for me.

Is that possible?
