AP Invoice Hold Rules - Options for where the invoice is routed

Summary:

The default routing for invoiceHoldsResolutionRule is the Task.payload/requestor (the Requestor from the Requisition/PO).

We operate in a Share Service environment where the person that we need to route holds to is not the Requester but the Requisition Preparer. Is it possible to create a Hold Approval Routing rule to route to the Requisition Preparer?

Content (required):

We would like to route invoice purchasing holds (match exceptions) to the preparer of the Requisition related to the Invoice PO. The default rule routes to the Requisition Requestor. In our environment, the Preparer is responsible for working with the Requestor to resolve any issues on behalf of AP. Is there any way that we can feed the preparer information from the Requisition to the Invoice in order to use it for routing these holds?
