Question : Cisco 7945 Phone setup in Call manager

Hello,
I am new to a company that has a Cisco IP Phone system using call manager. I need to setup an extra extension in one of the new offices. I have been in Call manager and poked around but I have never actually setup an extra extension before. Is there a way in call manager that I can copy an existing extension and make some minor modifications to add the extension or do I need to set each one up individually? I am a IT manager but have liitle experience with VOIP phone systems.
