Surface/Object buffer beyond glass?

[mrwiggles]

Hello Kray friends, I've a great question..as the title says, how can i get the surface and object buffers without glass?
Usually i do 2 renders, with a custom scene without glass, but i really would like to know if someone have a better solution.

In Vray for example there are multiple options in the Material Panel about selecting the output ID of the surface (Color, Color+Alpha, All channel).
In Kray could be nice have an option in the buffers panels, like "ID Exclude Trasparency" or "SEE THROUGH GLASS "

[jure]

For now the only way is to remove the glass and render buffers that way.
