Is your feature request related to a problem? Please describe.
Unit Frame addons often include opacity or "fading" options that check range or combat.

If you anchor an individual aura to Unit Frames, it's easy to use Set Parent to Anchor to have the aura match the parent's opacity, visibility, etc.

However, if you use multiple auras in a Dynamic Group set to Group by Frame - Unit Frames, you can't set the unit frame to the parent to match its visibility/opacity.

Describe the solution you'd like
Enable the Set Parent to Anchor option for Dynamic Groups that have Group by Frame enabled.

Describe alternatives you've considered
It's possible to simply create separate auras and anchor them individually to unit frames, but this loses all the benefits of a Dynamic Group.

Additional context
An example of an aura where I would use this functionality is Buds' Classic Buffs Missing:
