title: jira greenhopper rapid board release
body: <p>I am playing around with the eval of greenhopper and I set up a kanban rapid board that has a main bucket and several swim lanes.  The release button from the Done column adds any Jira in the Done column to a release.  </p>
  
  <p>Is there a way to just release a swim lane with that button?  So even though we have completed Jira in my main work bucket I might only want to release an urgent patch by itself.  It would be great if the release button had a few more controls over it so I could quickly just release a certain lane.</p>
  
  <p>or does it??</p>
