SSP one time address not available on added lines on PO

Summary: SSP one time address not available on added lines on PO

Content (please ensure you mask any confidential information):

When we have a one-time address on a requisition which get processed to a PO, the one-time address comes over to the PO lines without issue. However if the buyer needs to add a new line to the PO, the one-time address is not available on the newly added line. Is there a configuration to make that address available on the new line? If not, is there a workaround in order to add the new line and have it tied to the new line in some way?
