PO Workflow Signature and receipt date

Hello,

Does anyone know of a way to prevent the workflow from starting over if the expected receipt date is changed? (v2021 R4 (12.0.28) 

For example, a PO is approved, but the supplier calls and tells them there is a delay and the receipt date is changed. Currently the signature work flow starts again. They don't want to have to resign a PO due to the supplier pushing out the expected receipt date.  Is there a way from within X3 workflow setup or standard operations, not have the PO to go through the signature process all over again if the receipt date is changed?

Thank you
