Help with shipping zones please!

[snowy2007]

Hi all - I operate a UK based store.

I am using the zonetable weight based shipping module.

I have two zones defined - UK and Europe with different shipping rates for each.

The problem I have is that some zones within the UK (Highlands of Scotland and Northern Ireland) carry an additional courier surcharge.

Any ideas please of how I could compensate for this in Zen? At the moment if a customer is in Northern Ireland it just charges them the standard UK shipping.

Many thanks in advance.

Just to clarify my post above, basically I need to have Northern Ireland and certain postcodes in scotland classified as part of my European shipping zone rather than my UK shipping zone.
