we should have the ability to extrapolate a report for every send

When you re-send a report, you automatically get the reporting for all sends. But I think you should be able to get reporting for each send. Like, if you send a report in December, and then resend it in January, you should be able to see the reporting for just December's send. How it is set up now means that is impossible and you must see the comprehensive data for Dec AND Jan. Thanks for considering!
