Support reviews for grouped products...

Hi we have problem with grouped products and variants showed only in grouped products.

Our clients writed for us lots of reviews for product variants, but we can't show it anywhere (not all variant are visible individual).

Maybe it's possible to enhance reviews of grouped products and add support reviews?

How this can look:
In grouped product variant we add all reviews from "variants" in this products. This reviews have:
1. name of variant
2. author / rating / review
Reviews are good one for more conversions / seo etc. it's bad to don't show if have them.

Look at this topic. Is it your case?
What version are you using? Basically, it's possible to add reviews for grouped products, as well as for their variants.
