Title Page and Performance Notes Page

Some of my scores require a title page and most or all require performance notes, which are mostly text but will need to include a few single, stray measures. This might be a full stave if it's a piano piece, but if it's for, say, a quartet, I'm likely to want just one bass or treble clef bar by itself with some example notes and text.

When I do this now, I create a separate muse score project for just that page and use a PDF tool to sew together a title page made in a text editor, the performance notes page and the actual score. This works, but it's clunky.

It would be nice if there was a way in muse score to generate a title page and be able to include arbitrary measures. Or failing that, perhaps a way to include the performances notes project into the main project.
