title: Push different branch to Heroku
body: <p>Just finised work on my <code>other</code> branch. Now I need to test that this works on Heroku before I merge with the <code>master</code> branch.</p>
  
  <p>Is it possible to push the <code>other</code> branch to Heroku and it replace the contents of my last push which was from the <code>master</code> branch?</p>
