Multilingual Site with different shipping areas

Hi,

I have a website build on Wordpres WPML Woocommerce, main language is German, however we sell our products around the EU. Due to different currency value we had to give a different free shipment levels (for example: Austria ang Germany orders above 150 EUR are for free, and in Poland above ~300 PLN (70 EUR)
Your plugin corectly convert a PLN to EUR, however problem is that for Polish website it is using a German/Austria free shipmen order value, not as set Polish.

My question: Is there any option to have a different order values (per region) to have a free shipment?
