Screen Subtraction outside IBK

How do you guys add a hold-out matte before any processing is done on IBK?

I’m asking because I’d like to use not only the alpha, but the RGBA from IBK. Usually the Screen Subtraction operation from IBK output a good result, but if my matte have transparency on the core, the Screen Subtraction mess up too much the RGB colors.

Another option it is screen subtraction to be done after I supply a holdout matte. So any easy way to do that?

Thanks
