Hello Stephen,
The summary report unfortunately does not feature the ability to include a sub totals, or a 2 level report. You can only group additional fields or add cross tab columns, which will show the full total, but cannot show sub-totals.
This would be an enhancement request; which must go through User Voice.
User Voice is a new feature in QuickBase that allows users to submit their new feature requests, as well as vote on previously submitted ideas by other users.
You can access User Voice from your "My Apps" page, and then clicking the orange feedback button from the left hand side of the screen. You can also access User Voice by clicking the following link:
