Oracle eBS Promise Date - Automatically rolls the PO revision

We currently use Oracle eBS version 12.2.6 and our buyers in Supply Chain update the Promise Date which has downstream implications to ASCP and MRP. But Supply Chain doesn't want to update the Promise Date because it drives a revision to the PO which needs to be distributed to the supplier/vendor. Is there another field that can be used for the Promise Date that won't roll the revision on the PO? Or is there a way to not roll the PO revision when updating the Promise Date using standard functionality (preferred option)?
