Is your feature request related to a problem? Please describe:

I'm wanting to understand how my configuration will look without needing 4 characters simultaneously to test, Poison, Curse, Disease, Magic Debuffs"

Describe the solution you'd like to see implemented:

A "Preview" Button that shows how the Buffs/Debuffs will look on Raid Frames. Having a Test or Preview function to show how whatever buffs or debuffs are enabled.
