OJS3 sending reviews to third person / visibility review to author

I have three questions:

  1. Is it possible to create the option that a mail containing the reviews can not only be sent to the author, but also to a third person (e.g. a section editor)?
  2. If the review is handed in by the reviewer, this is immediatly visible to the author on the webpage. Nevertheless an editor probably first wants to survay and comment the review, before he wants to know that a review was handed in. Is it possible to make the author not see, that a review was handed in?
  3. And a third minor question: when I send a request to a possible reviewer, you have the option: “do not send E-Mail to Reviewer” What sense does this option make? Can I get rid of it?
    Thanks up front!
