The "create setlist from collection" feature makes a setlist out of everything that's in the collection, which doesn't address this situation.

It does, you just haven't found it yet.

Try this (you need Performance Mode disabled);

Open a Collection

Long press on a title - this opens up a page where you can select the tiles you want as a setlist

Tick each chart you need by short pressing it

Using dropdown menu (three vertical dots at top right hand corner) select "Create setlist from songs"

Name your new setlist and press done

New setlist, with selected charts, will now be under the Setlists tab.
