This reply only covers switching between set lists

These are suggestions:-

1) merge the two main setlists into a single set list (alternate the songs) prior to the gig
This has merits as you don't have to keep scrolling within a list (probably not an issue unless your gigs are long)

2) If you want to keep the two/three lists separate then include a few spaces at the start of each set list name.
This makes the lists appear at the top of an A-Z sorted list of set lists. i.e. it eliminates hunting for the list in the gig.

After the gig, select the set list name, press the overflow menu icon (3 vertical dots) and Rename it without the leading spaces; this puts the list in it's normal sorting sequence.
When choosing a gig name, I choose something like "Gig_venue 2022-08-25"; this sorts them by the name of the gig and by date (you can then keep old lists so that you can reuse elsewhere or avoid songs in the future).

Using one or both of these methods means minimal inconvenience and does not require Mike to make changes to MS
