Headers in Dashboards

I have a few dashboards where having the ability to add commentary to what is in a section versus the title of the report would be helpful for the viewer. 

Example: 
I have a dashboard for cancellations and downgrades for the month. I have 4 widgets at the top that sum up the number of accounts that have canceled/downgrade and are forecasted to cancel/downgrade for the month. But without commentary on what that widget is it does not provide the entire story to the viewer.
