title: Edit changeset comment after updates have been checked in to TFS
body: <p>I have just switched to VS2012 and being unfamiliar with it, checked in some major changes without a comment. No other updates have been done since then and no other developers will have access to the code for another few hours.</p>
  
  <p>Is there a way to add a comment to this changeset now thaht it has been checked in?</p>
