iputils woes

I have a slew of aliases to reconfigure the IP addresses of four eths to any of 22 configurations each.  For example, e11 runs sudo ifconfig eth1 192.168.1.10.  I figured I'd try to port them over to the ip command, but from what I've learned (no thanks to the god-awful manpage), it's not possible to change the IP address of a device with a single ip command.  You first have to remove the old IP, which must be specified even if there's only one.  Even setting my aliases aside, it looks like a script is required for a reasonable (ie. one step) method to change the IP of a device.  Or am I mistaken in my understanding?
