Create Directories by Role Access

I'm not sure how to explain this, but I'll try. I had installed WebFM with the hope that I could have different roles uploading files to different directories. These roles should have access to create folders within their own tree. So for example, if I have the following roles:

planner
admin
owner

... I would create a subfolder for each of them off of the WebFM Root folder and assign their role with access to upload files. This works fine. But I also want that role to be able to create/delete/rename directories under their folder tree.

Can this be done with the current WebFM? Or is this a new feature request?

Thanks in advance.
