Can a Return order upddate the Quantity received in the original Purchase order?

Hi,

My customer would like to use the Purchase Return order functionnality.

First of all, they receive quantities from a PO. There is no invoice at this step.
If an item is defective, they would like to send it back to the vendor, using a return order.
They would like to see that there's a backorder in the original PO.
The vendor will then send back a new item for the same PO and without any credit memo.
Last step, the customer will receive the new item in the original PO. Then the PO can be invoiced.

I don't know if there's a way I can do this and if NAV can update (like the Undo function) the Quantity received of the PO, using a return oder, so it's possible to receive an item twice. If not, any workaround?

Thank you for your help.
