MIDI Out from Up/Down + Tuner Switches

It would be very useful to me to be able to use one of three right-most switches to send MIDI commands.

I use an iPad (don’t) for lyrics when playing live and currently use footswitch H to send a MIDI command to go to the next song.

If the Up/Down or Tuner switches could be used to send a MIDI message via a long-press then they could keep their initial function and send a MIDI command simultaneously.

I appreciate this has probably been asked for previously but it would give me back my 8th switch for a Stomp/Scene change.
