Method to organize Project Templates into Folder Struture

I would like to have the ability to organize project templates into a folder structure. My organization has 10 different groups fielding requests, and within each of those groups at least 5+ templates for different project types with different timelines, tasks, etc. Without a folder structure to organize these project templates, the trafficking person (me) has to go through a LONG list of templates to find the correct one. To remedy this problem, I have given them long and clunky names, which makes it even harder to "find" the right template, however, the idea is that once I find it, the name is intuitive that it is without a doubt the correct template. It would be very, very nice to organize the templates with a folder/sub-folder structure, so that the correct template (workflow) could be identified in a much more efficient manner. ‚
