Lock down a device address in AirPort Utility

airport

I have one device on my network that does not use any form of rDNS or Bonjour, and I have to access it primarily through ssl. So I'd like to to stop moving around in the IP listing so I know where it is (instead of, as I did yesterday, assuming it was broken). Is there a way, through the AirPort Utility, to give a particular device, as identified by MAC, a specific non-changing IP address?
