Adding rehearsal marks and system text on multiple staves
There's been some conversation about how to add rehearsal marks and system text on multiple staves. (It's fairly standard in orchestral scores for rehearsal marks to be both above the top staff and above the string staff.) One possible suggestion is to use the same technique as adding voltas over multiple staves: Hold the Command key (on Mac) or the Control key (on Windows) while adding it where you want it. Until there's a way of doing this globally, this may be something that's worth exploring.
Thanks for your consideration.
