Workgroup PDM - How to generate conf. spesific report from the entire vault?

I´m using the Workgroup PDM Reporting tool in order to make configuration and revision spesific reports. (Configuration [in use], Revision [latest]).

This works fine, when I select only one product (one BOM) at a time. However, when I generate a report from the entire Vault (with all the products), it´s not possible to choose Configuration or Revision anymore. These options are coloured grey and cannot be chosen. Otherwise it works fine.

Any ideas how could I create config. and revision spesific report from the whole vault?

Thanks a lot!
