title: Is it possible to add custom options to VS2010's ctrl-. refactorings
body: <p>I am wondering if it is possible to add to the built in "refactorings" that VS2010 provides.</p>
  
  <p>For example - when cursor is on an interface, CTRL-. offers to "implement interface members".</p>
  
  <ol>
  <li>Do i have access to the actual macro/code that runs this ?</li>
  <li>Do i have access to actually add my own custom things to be offered in CTRL-. ?</li>
  </ol>
