Wish: "only in secondary"

[Micha]

Hi,

I'm using VfR and the material option "only in secondary" is one of my daily tools. But I found, it doesn't work in GPU mode. Is there a chance to get it in the near future? Is there an alternative?

I need to render small spaces like air plane lavatories and used the option to look through hidden walls, which are visible at mirrors in the room. Also I use the option to hide emitters which I used the get glow effects around objects like back lit mirrors.

I found a simple fully workaround. I post it here. The support of "only in secondary" seems to be possible.
