Another layer of Sub Folder

My organization could really benefit from one additional layer of Sub Folders. We are organizing workspaces by department, where the primary folder is “Team Personal Folders”, with a subfolder of each team member’s name. Due to this structure, we only have one layer of subfolder to organize all of our personal work. While I realize we could structure the workspaces differently, it’s not something the great organization wants to do because they want to keep the workspaces limited to department. Would it be possible to add one additional layer of subfolder?
