User Access – Granular

This looks like a great plugin. I am interested in the pro version and user access control at a folder level. I looked at the documentation here – How to give Folders access based on WordPress user Roles or to Specific Users – Premio – But the user access control that you have is at a role level for all folders. My scenario is I want a certain folder – lets call it system – where I put design media that I as the admin do not want the other roles to see. But the other roles can view other folders. How can I do that? That capability does not seem to exist. The user access control is at a higher role level and not at a folder level.
