Live set, multiple midi tracks on Novation Launchkey

Sup Reddit, I'm planning a big gig Saturday and gotta up my game. So far I've been opening up individual Ableton files and playing each song live like a noob, now I want to play them live from one Ableton file. Thing is, I got multiple midi tracks, one for each song, that I'd like to play with my NovationLaunchkey25. Is there a way to toggle between which midi track should be live without squinting at my screen onstage to press the 'in' button on the DAW? Would look a lot cooler if I can manage it from the Launchkey. Hope that made sense, TIA!
