Well actually, if you're still talking about a "reset" or "default" preset, you can attach that to your layout, then edit your layout details and set Send Layout MIDI to Song Selection. Then when you select a song, the layout presets will be sent, followed by the new song's presets. Would that address your situation?
Note the slight difference between sending these at the start of the next song versus at the end of the previous song, so it wouldn't work for something like resetting vocal effects so you can talk to the audience between songs.
