I want to have a different currency for different orders. So basically in the checkout page, either in address section or shipping method section, I will have a dropdown with different currencies. So now I can get the rates and change the total accordingly based on the webservice calling. But I want to change the order currency at backend aswell. Meaning in order summary section will have this new currency, in admin section all order processing with this new currency etc.
How to achieve this?
