visgroups

Is it possible to create new VisGroups that will automatically appears when certain entities/textures are used? Like how if you add clip brushes or game logic for the first time new VisGroups in the "auto" tab pop up.

I am having a visibility issue in one of my maps that I can't get my head around. Basically certain items in the map appear to flicker when viewed, but only from a particular location. I recorded this to help demonstrate: The spinning item you see is a func_rotating, and wall around it that...

So, I have recently come to learn that the blockbullets texture cuts visgroups. Does the playerclip texture do the same? I'm also curious as to what other utility textures cut visgroups.
