Payment hold on PO line

We want to hold a PO line for Payment hold.  We will receive the PO line when it ships.  We will enter the invoice when it comes from vendor.

But buyer want to keep the PO line on hold from paying it to the vendor.  Invoice should be paid when they release the hold on the PO Line.

Is there any functionality available to keep the payment hold on the PO line?  Buyers doesnt want to communicate manually with the AP team.

Also buyers doesnt monitor daily on which invoices came for which PO?
