Ability to switch GA profile IDs based on URL (dev environment vs staging vs live)

Hi there....thanks so much for the great module. Can't live without it. We were wondering how we might be able to modify it so that instead of simply giving the module a single profile ID, I could give it an array of IDs and accompanying URLs...i.e....

UA-12345-1, dev.mysite.com
UA-12345-2, stage.mysite.com
UA-12345-3, www.mysite.com

...then the module would know which of these IDs to write out based on whatever URL it found itself writing out GA code.

REASONING: neither me nor my clients can seem to remember to switch the GA account ID when we do a push from one environment to another. And inevitably the live GA profile drops traffic for a day or two as it's still being written to the dev account, etc. It would be nice if the module "remembered" for us. Not sure if I'm the only one who wants this, so I figured I would post here and see if anyone has any suggestions on how to do this, or if it should become a feature in the existing GA module.

Appreciate all your time and efforts,
Josh
