Does it make difference (in terms of not having to change the architecture) if you only make nested list entries possible in the setlist tab? Only like a subcategory if you know what I mean? So it's just a way to display several subsetlists (or "blocks") under a "master entry" setlist for a gig without changing the rest?

I was guessing too, that a setlist only is a list of song IDs and each setlist has a own ID too.
Thats why i was thinking, you could also add IDs of different setlists to a new setlist.
But as i said, i don't know enough about the app and i'm not a developer.
