Permissions to the folders in the File Cabinet

In relation to the permissions of the file cabinet, we would like for restrict the permission to view a specific folder in the file cabinet to each employee/user. 

For example: A user to be able to view only his/hers folder in the file cabinet and to be able to upload files only into that folder.

We are aware with the solution of creating groups and restricting the access of the folder to the specific group, although in order to be able to do it, we need to create each employee as a group.

Is there any workaround that can be done without creating a group for each employee?
