Pivot Table: Count zero when no associated records

When I create a pivot table and ask that it count the number of records I want to know which rows don't have any associated records.  For example, I created a pivot table with product and release, I then wanted to count the number of features associated with that release.  In this case, I also wanted to see which releases didn't have any features associated with it.  I can also see times when I would only want to see rows that have >0 items.  Maybe a check box on the field selection or the table settings that says "Show rows with no associations" or something to that effect.

thanks!
