Is it possible to change a supplier response to a PO from accept to reject in supplier portal?

Summary:

We have a business requirement for suppliers to view their responses to purchasing documents (PO, BPA, CPA) and the ability to change the response from reject to accept, or accept to reject.

For example, if a supplier rejects a PO, they would like to query the PO and change their response to accept.
