How to have random music loops vertically layered over a larger one?

Question

Hey y'all,

I'm trying to build a music track in Wwise with some random vertical layering. Specifically, I have a 48 bar arpeggio loop and want to have sub-segments of 8 bars play over the arpeggio in random order. How can I achieve this? As far as I know, a sequence container won't work since it'll play my arpeggio loop, then play the other loops.

Another question I have is if it's possible to randomly play one music track of a music segment. I'd like the arpeggio loop to randomly be one of four takes each time it loops around, but I can't figure out how to do this.

Thanks in advance!
