4-staff choir for full score and 2-staff choir for vocal score in the same document

For a Mass project I created a 4-staff choir in the full score as divisi to be able to display the staff label “Choir” without SATB and without a group bracket?

In addition the project contains also a vocal score.

Is it possible to create a layout with a two-staff choir (and piano grand staff) in the same document from the existing 4-staff choir?

Condensing for vocal staves doesn’t really work yet; so you would have to manually create separate staves/Players for each Layout, and copy the music from one to the other.

You could just use a text object, assuming you’re only doing labels on the first system. (Unless it’s something like a full orchestra, you don’t need abbreviated labels on every system.)
