Create your mini set lists as you want.

For a performance, long press the first mini setlist until a check mark shows
Then select the other mini setlists in the order that they will be played

With all required setlists checked, tap the three vertical dots at top right and select "Create Setlist from Songs"

For the setlist name, I use a format of "Venue yyyy-mm-dd". Assuming you keep old setlists, this means that the lists for each venue will be sorted adjacently  (using a-Z sort)
I prefer to put one or more spaces at the start of the Setlist name - this keeps it at the top.
After the performance, I remove these leading spaces to put the list in with other setlists for that venue.

After you have performed a few gigs, you may be able to just copy one of the old set lists when creating a new list.

Cheers
Geoff
