Can I see past monthly usage?

I seem to only be able to see the current months usage of forms and data.  Is there a way to see past months as well so I can compare usage from month to month?  This is just in the account overview.  

At this time the only usage is possible on the monthly basis since we are not keeping it longer than that.

You can see it in Account -> Usage http://www.jotform.com/myaccount/usage

The only way I can think of is to write down in some document what is the usage on every last day of the month - before the reset occurs to give you some personal usage data.
