Received not invoiced-customer owned materials

We regularly receive customer owned material - we used to just do a misc receipt to get these into inventory.

However, we are marking them as constrained materials so we don’t schedule the job until the materials are expected in so
we have decided to create a PO for such with $0 cost. All is fine with that EXCEPT they appear in the received not invoiced list. Is there any way to clear from here or will this just grow and grow?

Any other way to have handle customer owned materials (constrained)?
