Add a drop down select box to set the Sprint on a story/task/bug

Currently we do the following to add the issue to the sprint:
1. Browse to issue in issue navigator
2. Click "View of Board" link under Agile section
3. Select Board from pop-up
4. Right-click issue and send to the desired sprint

Fewer steps would be desirable.

A good way would be using a drop down box with auto-suggest and Ajax update on the "Future Sprint:" field (see attached screen caption.)
