How to create a Status Project that enable to create a Invoice associated to a PO but block new POs?

Summary:

I need to create a project status that allows the entry of an invoice linked to an existing purchase order within this project. However, this status should prevent the creation of new purchase orders and requisitions for the specific project, thereby avoiding the entry of new unwanted commitments. This way, it would be possible to create an invoice from a purchase order that was already committing to the project.
