nuova News

Good morning, I apologize for the trouble. first of all, congratulations for your plugin, then I wanted to ask for information if possible. is it possible to insert a different authors? I explain myself better: I am the owner of the site and physically insert the news I would like, however, not to show the name of my account but that of the person who physically wrote the news.
I also wanted to ask if it was possible to insert a date other than the insertion date? Thank you very much.
