How to Enable Multiperiod Accounting on Receipt Accounting for Uninvoiced POs

We set up Multiperiod Accounting to run in the Payables module, for invoices and credit memos. When an invoice/credit memo is matched to a PO line that has a Start Date and an End Date, the multiperiod accounting kicks off.
We also have a requirement to allow the Multiperiod to be ran and amortization to occur on receipts. This would happen when the PO is not yet invoiced at month end. Requisitioners would create a receipt for the entire PO value, which would be Receipt Accounted. Without the system amortizing receipts through Multiperiod Accounting there is a need for manual involvement. Please advise how Multiperiod Accounting is set up on Receipt Accounting.
