OpenRDX has the ability to filter as directly as you desire. You can configure a set of unitframes to show only your team by name or any combination you can possibly imagine.

To date I have not found ANY other mod that lets you sort and filter what units you see and how you see them as well as OpenRDX. I'd suggest using OpenRDX with Brethern Raid Frames as a good starting point.

The basic filterset has LOTS of options... but what you really need is a named set...


You set your window to show just those in a specific list, then it doesn't matter what group they are in, as long as it's party or raid they show.
