Oracle Agile PLM - Adding workflow attributes in advance search

I'm trying to search for change orders that are aging in duration. I need to include the approver name in the results, but i'm not able to do so using the out-of-the-box advanced search. I am trying to include the following in my search and search results:

Change Order

Status

Affected Item

Approver

Duration

Anybody have experience with this type of search?

Alternatively, is it possible to include the affected items in the OOTB User Sign-off Duration Report?

Thanks,

-Derek
