Add group name and group text for multi-staff part
As working with lots of orchestral scores by Stravinsky and Strauss to transcribe in braille, I found Musescore has a limitation that it doesn't allow entering group names and text applying to a group of staves such as a set of violin divisi staves. My thoughts are:
1. Add a group name which can show or hide. E.g., Horns as a group name, "I II in F" as staff 1 part name and "III IV in F" as staff 2 part name, instead of creating a grand staff for "horns" and inputting the part names as staff texts. If there's an instrument change on one of the staff (e.g., I II in F becomes I II in Eb), we can change it without touching the other one. This will save staves and computer resources. Musicxml already has a group name and a group abbreviation for a set of bracketed staves, so why not include them in Musescore?
2. The same applies to a text for group. E.g., two violin I staves with "div." in between, then "div. in 3" and then "div in 4" then "unis.". It's not good to enter them on one of the staves which is not logical. This is also available as a sub global sequence in the coming MNX, and Dorico can probably already do it.
