Currency code append to URL

Hi there,

First, great plugin!

We are looking for a solution to apply the “right” currency with appending the currency code onto the URL.

Could you please advise what have to append to the URL to force (for instance) the currency switch to USD on a certain product page? To make it clear: With that URL, a users should see prices in USD on a certain product page independently from the IP location.

Thank you!
