XBEE multiple

What's proper way to make multiple XBee controller?

I am not so familiar with XBee module. Only know how to communicate one to one and I am planning to make one controller that able to control multiple devices with XBee. What I can think of is have all remote devices with different PAN ID and switching PAN ID on controller every time. However I don't feel that's the proper way to do it. So, I am here to search for help and advices. Thanks for anyone who can help.
