Admin can store any documents in Doc Manager plugin. 

As shown below, you can create a user-specific docs to add documents for a student/employee. Ex.: Folder name - Registration Docs_2015

Once the folder is created, admin can search for the folder under User docs in search bar. After selecting the particular folder, the admin can add documents of the student/employee.

Note: User-specific docs will be visible only to the admin and the employee with Document Management privilege.
