Support for the "Alpha contribution" feature in Vray properties without turning on "Matte object"

I did a quick search and I didn't see this feature being requested. So here it is. I'd like to use this feature without enabling the "Matte object" option for my product renderings. Sadly, this scenario only works with CPU. With GPU I have to enable "Matte object" for it to work which is not what I need. So it would be really awesome if GPU would support this.

its requested for years but still not available....too bad.
