Duplicate zone definition

[ellivir]

Hi,
I realised that my shipping modules appear incorrectly in the main country because needed to modify the zone definition for the sake of taxes. Now foreign shipping costs appear in the main country or in the part of it. If I could duplicate that zone definition (because making it from the scratch, when there is huge amount of countries, is not really an option) and then just remove the unwanted areas (1 or 2), it would be great.

How to achieve that?

Would this duplication need that I would touch many database tables? What would be the safest?
