Create Pivot Table rpt always displaying specific date range

Create Pivot Table rpt always displaying specific date range

Hi,
is it possible to create a pivot table report that always displays a date range between days of the week?  I would like to create a pivot report that always show the records between Friday of last week and Thursday of this week without specifying date Ranges. I would like to embed this report along with other summarized data in a stateless from as a Dashboard.  I have the dashboard configured the way i would like it so I just need help figuring out how to automatically display Thursday through Friday records with out manually specifying date range.

Thank you very much.
