Need help with adding a 2009 calendar

I use season mode a lot and good at making schedules for each year but was wondering if anyone has some knowledge of adding calendars from future years into database. For example, creating a schedule for 2008-2009 using the 2009 calendar instead of 2007-2008 calendar and changing the year.

The game doesn't generate the schedule for future years until that season arrives, so I imagine it's just a matter of making the 2009 season schedule with all the appropriate dates, and then overwriting the file on day one of the new season. No guarantees that there won't be any issues - it's not something that I've tested - but as far as I'm aware, that'd be the only way to do it with the way the game generated subsequent schedules in Dynasty.
