I'm not sure if this is what you meant, but there is a template for marking articles as transformation articles. This template is called Template:TransformationArticle.

(There's also another template called Template:TranformationArticle, but, for reasons explained here, I turned that one into a redirect to Template:TransformationArticle.)

At any rate, whether this is precisely the template that you wanted, I hope that this template will help you somehow!
