@QWp6t I don't think I'm fully understanding the use case. Could you elaborate on the advantages of using this method versus using multiple rules based on Post Type?

For example if both Posts and Pages supported hero, could I not create the same result with two rules for "If Post Type is equal to Post" and "If Post Type is equal to Page"?
