Cross object autocomplete rule example?

Summary:

Hi, we have a use case to auto populate the Assignment Info section of a Job Offer based on the values of the Requisition that the Job Offer is from.

Content (required):

I'm not necessarily looking for the solution to this issue, but more so looking for an example of a cross object based defaulting rule. I.e: Assignment Info for Job Offer is from Worker Assignment business object, but the Job Requisition assignment info section is from the Job business object... so how do I bridge that gap?
