How to save Midi Remote set up

I’ve set up a very basic Midi remote just to control metronome level and on off in control room , for some reason today, the level was unmapped and I couldn’t hear the metronome at all until I worked out and remapped it.

Is there a simple way to save a Midi Remote set up ?

I did find this thread but I still cant see how to save a back up and name it -
