So after searching all over google and bing, I think I've come to an answer that I don't really want to hear, but there's no harm in asking here :). Is it possible to have unique permissions for a group that exists in both a parent and sub-site that has had its inheritance broken? Ex: Parent site has an owners group with John, Jake, and Sam. Sub-site has unique permissions and the same owners group but with Sarah, James and Nancy instead.
My initial thought when I was asked about this was to just create new groups in the sub-site with the appropriate users, but that was before I realized there are 100+ groups each with multiple users and six sub-sites that I would need to recreate them for. Is there any other way to achieve this, it would be a HUGE pain to have to recreate all the groups with the appropriate users for every single sub site.
