specific authors

Hello one question. you do not have any option for roles? in case I have an author role and I want him to be able to see certain options when creating a post. ?

and I have another question, There is a way to add social networks for specific authors. as for saying to share in my social networks in general of the site, but if an author in particular has a facebook page or an instagram and I want what he believes in my page is also shared in his social networks but being specified by author.
