Rick,
Are you using Application.cfc in your applications? If so, you could add the GA stuff to the end of the onRequest() method. That should cause it to be executed on every page request You might need to examine each request to make sure they aren't CFC or AJAX requests, but it should work.
There may be a way to do it with Application.cfm too, but it's been so long since I've used it I can't say for sure.
