Welcome to WebmasterWorld Guest from 220.127.116.11
I know I can do this crudely if set this up as a profile, but this only sees it going forward in time from the profile configuration.
Is there a way to see it going back in time?
This has been bugging me for some time and I don't quite know how I would google for this or look it up in some of the great books I have.
Maybe you can do this using a series of goals in GA?
