Generate tokens for subgroup paths

I've been using Subgroups to create nested groups representing divisions in an organization. This has become a problem as far as Path Auto goes, because it can only generate a path based on a single group. As it is, I've got to let all the group content sit in content/[title-raw], because there's no way to correctly place it. It'd be really helpful if Subgroups provided its own tokens that correctly output the complete group path.
