How to sort report filter values of Pivot Table in Microsoft Excel

I am using Excel 2007. I have built a pivot table. I have a field in the Report Filter section of the pivot. There are about 95 values in this drop-down. Problem: The list isn't sorted in alphabetical order. Or rather, for the most part it is, but not entirely. How can I force this Report Filter drop-down to sort values alphabetically.

The issue is that when you first create the pivot table a member list is created fore each dimension. As the source data of the pivot table changes and new members are added they just get appended to the bottom of the list. To fix the issue just remove that dimension completely from the pivot table, refresh the table and then put the dimension back again. The members should now be back in Alpha order... or at least that is how it goes in previous versions of XL...

This solution helps, if you have just one pivot table. I have an reporting sheet with more than 20 pivot tables, each of these having more than 5 fields. Therefore I am looking for an automated version to refresh the sorting within in the report filters. This would save me a large amount of time.
