Adding DFF Attribute Values to Requisition Approval Notification

Summary

We would like to add Descriptive Flexfield Segment Attribute Values to the Requisition Approval Notification

Content

Hello everyone!  I have a question about how to add DFF attributes to the Requisition Approval Notification.  We are curious about modifying an existing template in BI Publisher to include DFF attributes, which are being used in the Requisition in the Details section.  Has anyone done this?  Is there a good white paper or guide that provides a step-by-step procedure?  

I'm attaching the BI Publisher file as reference.  

Thanks in advance!
