Shortcut to select all on one stave

In Finale it was possible to select all the notes from one instrument/player with a click before the clef. It would be nice to implement this is Dorico. Now I have to select something in the first staff and choose for Select to end of Flow.

For that exact reason I’ve set Cmd+Shift+A as a keyboard command for “Select to end of Flow”. I don’t think it’s being used for anything else and it’s what I am used to in Sibelius.
