Vanzee,
I use my registrations as my playlists. I never go directly into my playlists, I just + or - thru the registrations. I also have an iPad Pro connected to keyboard with Songbook+. When I select a registration, the sheet music automatically pops up on iPad and as I scroll thru the registrations, the sheet music changes accordingly.
For me this is the easiest way to play song after song on a playlist, without ever changing a screen.
Give it a try.
