Folders in the rules engine

I'm still in implementation with GS but I see that very quickly we're going to have a ton of rules.  I'm being very strategic about the naming conventions, but it would be really helpful if I were able to create folders for the different rules to live in. Ideally there would be the ability to have folders within folders so that we can differentiate rules for Scorecards, Customers, etc and then within that nest other folders for rules that differ by segment.
