Traffic Management: Add 13-month trend to interface (estimated vs. actual)

There is no way to track estimated traffic level versus actual in the admin intterface. Adding a 13-month rolling window of data in the Admin Interface would allow users to immediately see if they are in danger of going above their estimated traffic levels. Whether you inherit report suites or manage so many you can't easily keep track - this wil be very helpful. See attached. Setting up alerts to go to administrators when one of their suites is above 80% - 85% of estimated traffc level would also be helpful.
