Need to create a report using the Assignment Process Status field

Hi,

Is it possible to create a report (SSRS or Excel Services) that includes values for the Process Status field that appears in the Timesheet and My Work pages in Project Server 2010 PWA?  A search of the Reporting and Published databases found no such field. 

As a note, the reason the report is needed is my customer is now noticing that in updating status from the timesheet (SEM), some assignments are not being submitted for approval.  These assignments show a status of "Not Submitted".

Thanks in advance for any help that can be provided.
