SUGGESTION: The Ability To Create Fences Within Fences

I would love to know how many people would like to see the ability to make sub-categories within Fences. Right now, the only way to do this is to create folders, but then we cannot see what is inside the folder, just the title. So please make a comment if you would love to see some way to have a fence within a fence, or something similar.

For example, when I assign several tasks to one of my employees, I would like to create a fence for that employee, and then sub-fences for each project he or she is working on, and then I can put in various files in the sub-fence. It makes finding them much easier. 

Anyone else wanting this ability?  An earlier post with this title had over 3000 people look at it. If Stardock wants to stay ahead of Microsoft, then this might be an option that appeals to lots of people.  Thanks for considering this.
