I need to set up a PC with CIsco Unified CM Administation attendant login

We have an older version of Cisco Call Manager, 7.1.5.30000-1. One of our main offices has a PC set up with the Cisco Attendant allowing the operator to answer calls with her computer. I have someone in another office that would like the same thing, but I am thinking I need to create a separate attendant login for her. I know the username and password of the attendant in use, but I am concerned if I log into another computer with it, it may bump her out. Does anyone know if the attendant can be logged in twice? If not, where can I create another cisco login attendant ID? All input on call manager is welcome
