In PTR we made some pretty extensive assigner stuff for that mechanic but I don't think any race guilds ended up trying to solve the mechanic in that way.
It would require code though

I got to the point of it assigning me a 1 or a 2

Catch all SPELL_AURA_APPLIED events and make a table of all destination names/guids.
Once you've got them all, sort the table.
Depending on the player's position in the table, show the Aura with their assignment.
