Need To Create Dynamic Totals in a Dashboard

I have created a dashboard for us to review our completed shipments. As shown in the screen shot below, it has several filters, and tabs to view the data in various ways. Along the bottom, there are four dynamic queries that respond to the selected row. I would like to add another query that dynamically shows the totals for Ship Qty and Total Value. Obviously, the users can enable summaries and sum these values, but they still have to scroll to the bottom of the data to see the totals, and they would prefer to have these readily visible and change depending on the currently selected data set. Is this possible?
