Changing Modes Via Midi Message (possibly feature request)

This really relates to any of the midi hubs but I am specifically using the stream controller. At the moment the only way of changing scenes is through the application but it would be great if a user could nominate a channel which would accept program change messages and could update the setting without having to connect to a computer (for a live set, for example). Is this possible and could it be a future update?

Either that or do you have a public repository where I could add the feature to the device myself?
