Version Specific Where Used Report for Drawing Formats

I could use some assistance with a report that shows what versions of the related drawings have a reference to a specific version of a drawing format.  Everything I'm seeing so far is based on the EPMReferenceLink database table, but from what I can tell this only gives a reference back to the master record (EPMDocumentMaster), not the version specific record (EPMDocument).  I have to believe that Windchill knows which version of a format is used by each version of a drawing.  Does anyone know where else this relationship might be stored?  Thanks.
