Unable to import author_id field to Woocommerce

When I use Woocommerce’s built-in import, I have no problem importing all of my fields except for author_id. I see no corresponding field for this to use with the sort by author option in your plugin.

What I’m truly trying to accomplish is to sort products by tags. Since I couldn’t figure out how to do that, I tried to copy/paste my tags to the author_id field as a workaround. If you know of a way to accomplish this seemingly simple task, I would be very grateful. Thanks.
