What an interesting thought. It had occurred to me that with the ability to insert pages and add text frames you could nearly create an entire hymnal a la InDesign (in terms of workflow) in Dorico already. The singular catch is the text flowing. I’m guessing that wont happen because the text is not its own “flow” like the music is. That said, if you have it planned out, you could still accomplish your goals, it would just have to be manual.
