I organize many things in many folders within Paper. I have a new project requiring multiple paper docs, and would like to share and collaborate all these with other users. When I try to share the folder, I receive an message saying that they need to be members of the parent folder in order to share this sub folder. I do not want to let them to see the contents of the parent folder, or the other sub folders of that parent folder. Is it not possible to only share a sub folder with other users?
