As I mentioned in an earlier post Jason has posted an application he wrote for Revit 2010. It allows the user to create sheets sequentially avoiding the opening and closing of dialogs that the existing process in Revit requires. His post has a video the demonstrates the tool in action as well. He also provides a step-by-step process to get it installed.
A still faster way to make sheets if the actually naming isn't very important yet is this TIP.
