Is your feature request related to a problem? Please describe.
I'd like to be able to track specific combat log events that happen to my character's guardians.

Example:
I'm a Shaman, and want to track when my Grounding Totem absorbs a spell, or when my Tremor Totem is destroyed by a player.

Currently, I can check if events happen to any friendly pet/guardian, but I can't specifically check for my pet/guardian. Hunter pets are fine because you can use the UnitId field to check for playerpet, but Shamans' totems have no UnitIds.

Describe the solution you'd like
WeakAuras already includes options for checking Controller Affiliation in UnitFlags:

I'd like to see a third option added to this dropdown that checks COMBATLOG_OBJECT_AFFILIATION_MINE. This would probably require the "Source In Group" and "Destination In Group" options to be renamed to "Source Affiliation" and "Destination Affiliation" or something similar.

Describe alternatives you've considered
I'm able to do this with Custom Triggers, but it would be very convenient to have it built-in for all the dynamic information.
