Currently a setlist is a folder where you can store presets. I would like the option to create setlist which link to,a preset. So I can have multiple setlist referring to the same song(preset). So when I update the preset, all my setlists have the same version.
+1 for this.
IMHO a setlist is the order to play a list of songs in - not the presets for those songs, which will be pretty static (apart form a bit of venue specific eq).
We often change the set list using a pool of songs depending on the event. Not needing to create multiple copies would be way simpler and more logical (and less prone to cocking up )
