Original currency on checkout

-- HikaShop version -- : 3.0.1

Hi

I have a setup with a multi language and currency site, where each language has it's own currency. I've modified the code on products to only display the original price.

My problem is with checkout. If user adds a product with original price in €, then it's converted to main currency on checkout.
How can I prevent this and show the price in the currency the product has?

The site is set up, so the cart is cleared if the user changes language, so there will only be the original currency in the cart and only one currency.

Thanks

This should be part of the default HikaShop installation IMO.
