I have a Soprano Section, which then get Divisi-ed into two. It needs to go into three a bit later on.
To create “three from two”, I added another Divisi flag, but the third staff doesn’t show up in the same system as the flag. It shows on the next system. It shows in Galley View immediately from the flag, but not in Page View, even with notes in it.
Is there a trick to augmenting an existing Divisi?
