Default Can you have multiple calendars in WM2003?

Might sound like a weird question but a friend was very interested in my XDAII but said he wouldn't swap his Palm V for one (!) because he thinks it's not possible to have more than one calendar (or schedule) in WM2003. He has 2 schedules on his Palm V. One shows all his appointments and the other shows all his colleagues appointments. Both schedules are syncd with the Palm Desktop software (or so he says).

At first I thought it shoud be easy to have more than one calendar on my XDAII (but the more I look at it the less convinced I am that it is possible.

Would he need a third party app for this, and if so does one exist?

Cheers
