Reflect and Refract as mask (render pass)

It would be cool to be able to use refraction and reflection as mask for IDs masks. It would be very useful for large-scale productions and I have a real example: Imagine a product that is about to launch globally. The briefing is the product coming from inside the ice piece, exploding it. The product has a label with a description. Each video will need to be in a specific regional language. No deadline to render 40 different languages, so the solution will be changing the label in the post, which is possible through UV pass comp. But the refraction and reflection will need to be editable in post to, accordingly to the product label switch. The reflection and refraction ID masks will help with this.

As an example, I'm using another render engine(RS) that support this in the image below. The Red Green Blue are ID masks set in the material level. Note that the RED ID(product label) is affected by the GREEN ID refraction(Ice shader). Making possible the special selection of the RED ID behind the refraction.
