If you’re using the default author field from the Post, no because that’s automatically assigned, but you can Extend Posts and create a new relationship field to Users at the Post level for additional authors and then do what you’re suggesting above. You’ll need to modify your template to loop through your relationship field, but that’s not terribly complicated (either in PHP or with our Pods Template language).
