Cisco Wireless :: 5508 Assign Single Ssid To Multiple Interface Groups By Assigning Ssid To Multiple AP Groups

Is it possible to assign a single ssid to multiple interface groups by assigning the ssid to multiple AP groups? 
 
I have buildings geographically dispersed that are configured with multiple vlans in interface groups so that I can maintain an addressing scheme of dhcp assigned addresses per building.  Each building is also further grouped as AP groups.  I'd like to know if by assigning the same wlan ssid to each of the AP groups, will I maintain addressing integrity for each building?  I'm thinking it will work.
 
Do the buildings have to be outside AP range of each other to avoid problems?
