title: Azure Devops with Git only suggest Pull Request for latest commit
body: <p>we have recently switched to Git inn Azure Devops (from TFVC) and I am struggling with Pull Requests:</p>
  
  <p>1) I created one branch from Master and committed some changes on that branch. I did <em>not</em> do a Pull Request at this time.</p>
  
  <p>2) Then I created a second branch from Master (without the first branch's changes!). I committed changes on that second branch.</p>
  
  <p>Now I wanted to create a Pull Request for the first commit. 
  But in Azure Devops, I only get suggestion to create a Pull Request for the latest commit!
  I can't find anyway to create a Pull Request for the first commit, unless I first do the second (which I did not want to do in this case).</p>
  
  <p>Is my way of working not supported by Azure Devops with Git?
  (I assume this can be done with command line Git, but I would like to avoid that when I'm already working in Visual Studio and Azure Devops.)</p>
  
  <p>Thanks for any help!</p>
