How to default Payroll based on Recruiting Type

Summary: I am looking to default the "Payroll" field in the Payroll Info section of the Create and Edit Job offer page based on the "Recruiting Type" selected in the Create Job Requisition page.

Content (required): In the feedback section of the use case submitted in the COE it says this rule can be achieved using the Assigned Payroll business object and Object Defaulting Rule Type. However, it seems like there is no way to pull in information from the Requisition. Does anyone know of a way to pull information from the Requisition into the Assigned Payroll object?

This is the field I am trying to default in the Payroll Info section of Create and Edit Job Offer page.
