Sith Raid UI Clarity

Since the raid economy rework, there has been a lot of confusion around phase 4 of the Sith Triumvirate raid.

Because Darth Nihilus's and Darth Sion's damage is tracked on a health bar and does not contribute to raid progress, many members of my guild are assuming they are doing 0 damage to either Nihilus or Sion.

I would like to request an update to the UI that can show the amount of damage applied to Darth Nihilus and Darth Sion, without any changes to the actual mechanics of raid progress.
