Export csv with product prices based on countries

I have several hundred products on my woocommerce store and I sell in various currencies using your plugin.
I can’t set the price to a default exchange rate and have to manually update the products.
I don’t want to have to manually update all of these products but I wondered if there is any way to import via csv file?
Instructions would be much appreciated.
