Is there any way to make it mandatory for users to set up featured image when listing a product?

My website users are listing products but some of them completely ignore or do not notice setting up featured image which obviously causing missing pictures in global or local products grid display. I can go back to their store and fix it but it's getting too much of a job to fix it. Is there any way to make it mandatory (validation rule) for users to set up featured image when listing a product?
