Reporting on document attachments

Summary

Performance Document attachments specifically

Content

Hi, does anyone know if it's possible to report on any attachments that may have been added?

The specific example is where one or more attachments have been added to a Performance Document, I want to be able to report their presence and the attached document's name if possible? Presumably the documents is stored somewhere and the path to it saved against the Performance Document so it can be opened and viewed in situ.

I can't see anything in the Workforce Performance subject areas in OTBI but perhaps someone knows how this can be done some other way (e.g. BI Publisher?).
