Can I upload a master tracking table? [google.com]
At this point, we are not able to upload master tracking codes or custom lookup tables. Once master tracking codes and lookup table uploading are resumed, we'll let you know with a message in the Google Analytics interface or by email.
maybe if enough people go read that and click "not helpful" someone will get on it.
A rep of a travel company told they were using it with Analytics because they spent that much on Adwords that Google helped the-m in this case.
But I can't confirm it this was true or they were simply Urchin.
You may identify a website using this because they use &utm_id as a parameter in the URL.
