title: How to not notify reviewers Github pull request?
body: <p>Suppose I am working on branch called <code>feature_one</code>, and I have an existing pull request on Github, someone comments on it and requests changes.</p>
  <p>So I amend the commit in <code>feature_one</code> with the change and do <code>git push origin -f feature_one</code> so it goes to the remote branch. However, I don't want it reviewed yet, but it still notifies reviewers, how do I avoid this?</p>
  <p>In other words, how do I preview the whole pull request and manually send it for review rather than auto send with a push to remote?</p>
