I would also like this feature! 😀
It seems that this feature is mostly standard on hardware backingtrack players. I name it like this:
01 uptown funk
02 uptown funk
03 uptown funk
04 uptown funk
…
and then
01 will be routed to output 1
02 will be routed to output 2
…
Right now i need to assign 8tracks for 40 songs manually. Pretty sure i mess up something when clicking 320 times 🥳
