Importing featured visibility

I am trying to import the “featured” characteristic of a product. I feel the answer lies somewhere in the taxonomy section, but I don’t know how to continue. I tried replacing “visible” with “featured”, which leads to a partial success. It gives an error message and only imports part of the product data. I can see the fields in the export but I don’t know how to import them. I can run the importer twice, once with “visible”, then after with “featured” in this field, and the result is what I want, but I feel there must be a better way.
