Sorry, just a newbie, but what requires you to enter multiple routers? Are you just needing to be able to go from one base station to another? if so? Why can't you just set it up to automatically connect to accesspoints from the airport menu in your menu bar? If you need to be able to use any sort of encryption, or if there hidden access points(not broadcasting network name), then entering the network router's name and address (i.e.) 10.0.1.1, etc. I don't know if this helps or not, but take a look through the Airport Menu icon, and then select "Other..." Hopefully this helps.
