body: <p>If I create a custom Build Definition Template from the context menu below, how does one actually edit it?</p>

  <p>I can see I can delete it, but not edit. Are Overwrite or Delete &amp; Recreate the only means to edit the Template? Seems a little severe... Neither option seems to give me historical tracking...</p>

  Or am I missing something obvious?</p>
