CC/GPIO 1/0 different functions

It would be great if there could be a different function for 1 or 0 on a gpio port.

For example: external button pressed (1) recalls snapshot A and pressed again/released recalls snapshot B

User case: having a foot switch to recall snaps for a guitar solo. So I can change for example panorama & fx muted for a guitar solo hands free while mixing.

or change com busses to have a chat with a certain musician as monitor engineer: snapshot changes routing of my talkback mic to just one mix and the musicians talkback is muted on all other busses than the coms
