[Koha] Movie cover images

We don't subscribe to any enhanced content services, so Amazon is our only feasible source for movie cover images in the preferences. Amazon does not seem to assign ISBNs to movies, however, only ASINs. Has anyone found a way of getting images to display correctly using the ASIN, UPC, or other identifier. Koha relies exclusively on the ISBN as far as I can tell. A sample movie for which we have no cover image: Madagascar 3 (UPC 097361169941). We have Koha 3.8.
