title: How to do pull request in TortoiseGit on already pushed changes?
body: <p>The standard approach is described <a href="https://stackoverflow.com/questions/26988891/how-can-i-make-a-pull-request-using-tortoisegit">here</a> but I've already closed the push window, so I don't have a way to click <code>Request pull</code> button.</p>
  
  <p>Is there any way to create a pull request on already pushed changes?</p>
