document management visibility of directories

hello,

Is it possible one day to be able to apply a restriction on the visibility of directories per project in the tree structure? each project is different and requires specific and advanced document management. Currently, the list of document directories is well filtered for the project, on the other hand the tree structure always displays all the folders. This would notably avoid seeing empty and useless folders in certain projects and adapting a specific documentary organization to each type of project.
In my organization, this is the need that comes up from many projector testers.
Thank's
