如何将其他数据导入woocommerce产品变体

Question

We've got a webshop with about 300 products with variations, each variation has an unique sku. I do all updates/changes with wpallimport and a csv file that contains sku's, prices, description etc. Now, I am trying to add the delivery time for each variation (two possibilities, 1-3 days or 14-30 days), but I am kinda stuck on how to do this. Been looking into just using the "product variation description", but for some reason wpallimport is not able to find it (same goes for adding custom fields, it's not showing up in wp all import). Is there another way of doing this? Could I somehow just add it as an attribute or is there a better way of doing it?
