Hey @dth122,
AbleSet 3 will support adding a delay after a song from within the setlist, along with other per-song customizations:
If you’d like to give it a try already, you can download the latest beta here: AbleSet 3.0.0-beta.12
I’ve tested this version thoroughly, but there might still be bugs I haven’t found yet, so I’d advise you to test this on your set before using it live.
Let me know if this works for your use case
