I want to be able to add my FX Channel into a Bus Folder on the mixer.
Use case example:
I have two rhythm guitar tracks in a RHYTHM GTR BUS, both those rhythm tracks are routed to an FX channel with a delay inserted. That FX channel is also routed to my RHYTHM GTR BUS. When I collapse the RHYTHM GTR BUS, despite being routed to the bus, my FX channel remains outside of the collapsed folder.
I use the folders to clean up my mixer, if kind of defeats the purpose if I can't collapse all the tracks feeding the bus.
