Is your feature request related to a problem? Please describe.
Some UI's (including mine) uses party frames until we get more than 5 members. Regardless of it being a raid or not.
WA's that should only be effective while in a "party" thus cannot reliably be activated based on the current group-options for load conditions.

It's a minor request, but it would save me from having to add custom triggers to each aura to check for group size.

Describe the solution you'd like
New sub-option for "In Group" where you can select "Group Size", and input min-max.

Describe alternatives you've considered
Alternative is to add custom triggers to each single WA. Perfectly possible, but extremely tedious.

Additional context
NA.
