Mass Update of Supplier Records

Hi -

We have a new ship-to location address that will replace an older address.  The problem is that all the supplier site records are populated with the old address as ship-to-location.  We can set the new address as the ship-to location on the organization and buyer level, but the supplier site setting still has precedence.

Is there either a work around for this or a method to mass update the supplier site records (to set the ship-to-location to null or to new address)?

Thanks
