I have searched around the forum for a week, and found answers to almost everything, but not this;

In my store you can use two different currencies. When it comes to taxes I have managed to set it up so if the shipping adress is within a zone the tax will be added (in my case VAT if the customer is from the same country I'm shipping from).

My question is; is it possible to do the same with currencies? I have 2 different currencies, GBP and Euro. but for UK citizen I want the order to be charged in GBP, and not have the option to choose euro.
