Don't know if this is what you are looking for....
However, we never use the date wizard in any reports. We have a calendar table on our database which contains data up to 2011 in columns such as day name, week number, month name, day number, year, etc. etc. We join to the production tables on any date column to a columns on the calendar called actual date, this column is simply a large list of dates i.e. 01/01/01 through to somewhere in 2011.
All of our time dimensions are sourced from this view.

Adam.
