[Koha] Librarian Privileges

Hi, How does one tie a librarians user ID to a specific library within Koha? As it stands, if I create a librarian ID, they can choose which library they want to manage. However, is there a way to tie the ID to a specific library such that they have access to the patrons and books within that library only? Thank you.
