Momentary option for user assignable buttons

Hey folks!

It would be super cool to be able to have the option to set user assignable buttons to be momentary for certain circumstances such as FX send unmute/mute, or return volume to a percentage, or even have a scene recalled @ on, and another @ Off. I do this frequently for various midi functions on other surfaces. It came up at a show yesterday and I was surprised momentary vs toggle wasn’t an option!
