How to account for VAT when the SHIP-TO address in Oracle is not the final SHIP-TO location?

under EU law, if your customer arranges for the freight of items or if they ask you to deliver to a dock for example in your own country then you need to charge domestic VAT - which of course is not what your customer wants. If the customer can provide sufficient proof that the goods are moving outside of the country then you can indeed charge the VAT accordingly.
How can we record the 'Final SHIP-TO' location when all we have is the SHIP-TO address that could be the port in your local country?

any suggestions on how to accomodate this, whether Oracle should or if this is something that should be manually maintained?
