I would love to have the ability to edit song sections within the setlist, similar to how you can already delete and rearrange the order of songs on that page.
Thank you for all the new features!! 
Hey @Adam_Molinaro, thank you for your feedback!
This is kind of possible using the Automatic Jump notation, though you can’t do it within the setlist editor.
I’ll see if I can add a more visual method of changing the order of sections.
