I can think of one possible way. If you go to www.honda2001.com and go through the links to configure a 2002 Odyssey, you can add accessories while you configure the vehicle. At the end, the configurator quotes you a price for your configuration, including labor for the dealer-installed options. It tells you what the hourly rate is that it assumes for labor. From there you can work out how many hours each dealer-installed option takes.
