I use pitbull 3 which allows you to statically order your party (alphabetically) and filter who you want to see in a raid by party and class. Unfortunately, you have to manually adjust this each BG match depending on the groups your team gets split into. It's not a perfect solution by any means, but the best ive been able to come across sadly

I will have to try out this Lunar Frames that Fizzler mentioned, the custom party filtering sounds promissing!
