Cross-Subject Area Report with 'Security - Roles and Privileges Real Time'

Content

We are in search of a report that would require a cross-subject area analysis using Worker Assignment Real Time and Security Roles and Privileges Real Time.  I am familiar with creating cross-subject area reports within OTBI; however, it doesn't look like there are any folders/fields within the Security reporting subject area that can act as the 'connector' to another subject area. 

I've attached a screenshot of what we are looking to pull into this report (the grey indicates the items that we can pull from the Security Roles and Privileges Real Time; orange are the fields that we are looking to add, as they don't seem to be available within Security.
