Great Idea for Guardian System? Move the area/walls manually from inside your headset

Why cant we move the walls to the right position inside our headset. This would be awesome.
For example, push or pulling the virtual grid walls in any direction to get a better sense of the true boundaries.
It is probably easy to adjust as well.
I know it annoys me when the sensors cant see the touch controllers.. and it is painfully slow.

Thoughts?
