It would be nice to expand the transpose feature so that it allows you to do just a section rather than a whole staff. This would be useful if you want to reuse notes (copy) from another staff in a different clef. Then you wouldn't have to re-key them in the right staff or copy to a separate document and transpose & copy back.

To answer your question, yeah, but in the meantime an easy work around - copy the section to a separate, temporary staff, do the transposition and copy back
