Yes indeed, but – sorry, by the “solo staff issue” I meant the behaviour where, when I try to add a soloist above an existing staff, what actually happens is that the existing staff is changed into the soloist staff, inheriting its existing music, and an additional staff appears below, empty. This adds some extra steps required to move the existing music down to the correct staff before adding any soloist music, and makes it thereafter impossible to (for instance) select the entire soprano line in one go.
