Is your feature request related to a problem? Please describe.
Evidently the retail version has load conditions tied to dungeon role (ie based on UnitGroupRolesAssigned()).

Describe the solution you'd like
It would be nice to have this in Classic too.

Describe alternatives you've considered
I tried making a weakaura with a custom trigger condition on the relevant events, but ran into problems.

Additional context
This is for dungeon role. Not to be confused with raid role (ie Main Tank, Main Assist).

Talking on the Discord server, someone suggested a fix that made my custom version work. It can be found here: https://wago.io/YxWtC19N5

This feature would still be nice though!
