Provide external parties with attachments

Hi

When we release a BOM, there are a number of different files that need to be provided to different external parties, eg: 2D PDF's to suppliers of mechanical parts, PCB fabrication files to PCB fabricator, software to , etc.  And there are files that we attach to parts in Agile that we don't want to be sent out to anyone, eg: Altium ECAD fiIes. I understand that other than provide the external parties with online access to Agile, the best way to provide these files is to export a PDX file.  But I want to be able to create different PDX files for the different suppliers, containing only the files that they need.
