We need to make the system ask us for a receipt in Oc's services

We are about to implement Supplier Portal but we have an issue. We noticed that when a PO is for services (non-inventory) and is created, the supplier in the portal can immediately invoice the PO. This is incorrect for our business, we necessarily require a reception even if it is not merchandise.

Is there a way to make the system force me to create a receipt before the supplier submits its invoice in the portal?
