How can I add the requisition name to the "PO Reference" generated by the quick sourcer?

When using the "eProcurement > Buyer Center > Quick Source Requisitions" feature, it puts "Online Src From Req <RequisitionID>" into the created PO's "PO Reference" field.  Is there a way to change what is populated there to include the Requisition name as well?

Example Purchase Order

Purchasing > Purchase Orders > Add/Update POs

Example "Requisition Name"

Purchasing > Requisitions > Add/Update Requisitions
