Hs Code & country of origin export for click and drop

Hi

When doing an order export from Shopify to a csv file to upload to Royal Mail click and drop, does anyone know how to include the custom information fields for HS code and Country of origin so that I don’t have to manually put them in.

Thank you

Amanda

I can’t believe this is still not available within Shopify, Shopify support points you to a $20 a month app.

Absolute joke.
