A workaround for the double tap to stop and Outro KILL is to hit the right switch for a pause(one of the switch pedal settings)… then change songs.
BeatBuddy was actually designed like that, but nice tip nevertheless! 
After you press the Right Switch to Pause, you can HOLD the Main Pedal and it will stop. Just in case you want to use the same “song” again…
Hope that helps…
