How to gather all PDF files for an assembly?

I'm sure this is simple because it's something so many people need to do...  In PDM Pro how can I gather all the PDF files associated with an assembly?  I want to be able to select the top level assembly and find all the PDF files associated with all the drawings for the assembly and it's sub-components so that I can send them to shops for quoting.  I'm using a task to generate PDF files from .slddrw files during state transitions so there should be file references between the drawings and their PDF files but I don't see a way to find all the PDF files.
