HS Codes and COO sync to online platforms

So this month a new release was brought out with HS and COO columns added on to the product CSV upload BUT this information does not sync with Shopify. 

PLEASE can you look at integrating this information to the online platforms? If we do an upload directly to Shopify instead with a CSV, we then have issues as it changes the product ID and the stock levels no longer sync with DEAR :( As these fields are available on product listings in Shopify, surely there should be a way to push that information to DEAR? I have been advised that we can push it the other way round but that does not help.

Thanks
