How can we find the Number of Resumes in Taleo Enterprise Edition

Content

We need to find the number of resumes currently held in the Taleo application.
Taleo Metrics does not seem to specify this exact data.

In OBI link from Taleo I have run the Candidate report but it is not reported on whether a resume is attached to the candidate or not.  I tried to find any 'resume' option in the Subject areas, and also created a new report, again no joy!

The client only uses Taleo for CV holding and creating vacacnies, but the resume/resume parsing options are available so I would expect to see them in the subject area.
