To assign new rooms within a clinic you must first head to the Administration section.
Once there you must then navigate to the "Branch Settings" tab.
When you are in Branch Settings, you must find "Rooms" then correctly type the name of your given rooms with a comma inbetween the room names.
Once you do this, you can head back to the main screen and on the top bar you can can select the room you are currently working in.
NOTE: when you change the name of a room, it won't be available in the appointment screen, therefore any existing appointments in those rooms will dissapear. In BeeFree Version 4.10 (Nov 2014), the old room will be displayed with a * (star) against it until you remove all appointments from that room.
