Feature Request: Modifiers for player head switch to FPFC camera position when FPFC is enabled.

[Mawntee]

It would be extremely helpful for debugging purposes if this was able to swap back and fourth between headset object when you're actually playing in VR, and the FPFC cam when you're just trying to work on an effect in a map.

Constantly having to restart the game and switch back and fourth just to see if a single thing works is CRINGE!

(obviously not expected for hands though - when working on a map someone can just use head pos to debug then swap back if needed)
