Hello Tommy! I don't see a way to do this currently, but will go ahead and submit this as a feature request for inclusion in the future. In the meantime, you can likely set up a throttling limit on your domains for X MB (whatever you want the upper limit to be) and then add an event under Settings>Events to send you an email/notification if/when that throttling limit is reached. That won't tell you exactly how much bandwidth was used that day, but it would alert you to higher than usual bandwidth consumption. 

Hi Tommy, since Kyle submitted this as a feature request I changed the type to an Idea, Under Consideration.  This will make it easier to update in the future.
