Interface Statistics on Dashboard: Period of Report?

[beremonavabi]

Is there someplace in pfSense where I can set (or even show) the period for the Interface Statistics widget on the Dashboard?  I'm not looking for a way to set how often the widget refreshes.  I'd just like to know if the traffic totals it shows are for a day, week, month, or perhaps since the box was booted and change that to something else.
