Can Garageband ioS change instruments via MIDI Program Change message

Hi All,

In a live setting is there any way for GarageBand iOS to change the currently selected track by receiving any type of MIDI program change? Basically I have a song where I need to play 3 different sounds/instruments throughout. I can assign each instrument to a track easily enough, but there's no easy way to switch tracks on-screen. I was hoping to be able to send MIDI messages from my floor controller to do that.

Thanks.
