Updating the Interim point count in Player Destruction

[Sappykun]

I'm using the Player Destruction HUD as a makeshift progress counter for one of my maps. Players cannot score points directly.

Is it possible to increment/decrement the team's current stored point count (circled) without giving specific players points? I want to use it to measure something unrelated to the team's progress.

As a bonus question, is it possible to disable the striped portion of the BLU progress bar?
