Could you script and schedule say a daily 1 day report, store the result, and have a script to get the last 30 (or whatever you want) days?

That is possible. Annoying that you can get the last 10 days in a second but need to duct tape together something if you never want to interface with the gui and then instead of a few hours you have to collect the data over the entire 30 days (but only after you start doing this).
