Multiple staves on percussion question

[bmomusical]

Hi everyone. I have a marimba part that on a few occasions play various other percussion instruments. All instruments are part of the same player (the marimba player) and I entered everything in Galley mode. First, I would like the instruments to be labeled to the left of each staff so that the percussionists knows what to play. See image below. Is there an easy way to do this?

Secondly, I already noticed that I could not add cues to percussion instruments that are not the initial player (the marimba). Is there a way to override that?

Staff labels are determined in Layout options >Staves and systems first options.
You could give the instruments to different “players” and assign all these players to a single layout. So you have all the possibilities
