SO_ShipToAddress Ship To Code Modification

Hello everyone,

We are trying to merge similar customers in SAGE 100 2020, and we have discovered that ship-to addresses with the same shiptocode are being overwritten by the source shiptocode if they are identical. Is there any way to modify the shiptocode of an existing ship-to address? I couldn't find such a utility and we are worried about history if we make a new one.
