I'd like to import an article asset and make it a child of another article

We have a series of articles about cooks, with related articles (2-4, usually) containing recipes which were contributed by the cook profiled. I'd like to import the recipes from NITF, but don't see a way to say "this article is a child of article {ID}". Is there a way to do that, which I'm missing? If not could, could a way be added? Thanks!
