title: How to add a link to already opened pull request on github?
body: <p>I am a noob to github's organziation settings and all. Don't know if we need these settings for the question Im about to ask.</p>
  <p>So what I want to achieve is to show the already opened pull request's link on a subsequent push. In the past when working with bitbucket and gitlab with a development team, the link used to appear both on the initial push to create a pull request and also on subsequent commits push to PR. But in my current workflow it only appears on initial push to create the PR. (<em>Note</em> I haven't been setting up repositories in the past myself and just starting to explore this area so no idea if in the past lead engineer has been adding any settings or not)</p>
  <p>This is what I see on initial push:</p>
  <p><a href="https://i.stack.imgur.com/nYbjf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nYbjf.png" alt="enter image description here" /></a></p>
  <p>And this is on subsequent push. No link to already opened pull request</p>
  <p><a href="https://i.stack.imgur.com/fZ7K9.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fZ7K9.png" alt="enter image description here" /></a></p>
  <p>What am I missing? And is it even possible to do?</p>
  <p>Any read or keywords to search for would be appreciated.</p>
