Filter by Summarize on Dashboards


Does anyone know if you can filter a Dashboard by the Summarized number? I have a Dashboard that Sums the Job Required Qty for a Part and displays the Average On Hand Qty for that Part. The Dashboard is sorted by Part so it will show:
Part:3001 with a Job Required Qty SUM=100 and On Hand Qty AVE=200 and I want the Dashboard to display the Part if the SUM is greater than the AVE. Any ideas? Thanks!
