CURCY Force Currency for Specific Checkout Countries

Hello. Our store is based in the European Union. Due to brexit, most of our clients have to pay extra import duties on their orders, and we’d like for our business to pay the taxes.

To do this, we’ll use the fixed price method of curcy, but we would need to be able to force the checkout curency to GBP if the shipping address is in the United Kingdom. Basically prices in GBP would include import duties as well. Could we use any kind of code to achieve this?

Thank you!
