Yeah, I can't figure it out.
I got this from S'rendarr (see spoiler):
I tried adding 39076 and 47083 to "Prominent Buff & AOE Assignments" "Aura Whitelist 1" "In Display Window [1]" and it didn't do anything for me.
I'm not API savvy enough or S'rendarr savvy enough to do this myself.
That's why I made an addon request.
