Multi-selections in Calendar Web Control

[Nsynan]

Is there a way to do multi-selections in the Calendar Web Control. I know about the WEEK and MONTH selection, but I need a means to pick and choose the dates to add to the .SelectedDates collection, say like:
1/6/2004
1/11/2004
1/13/2004
1/21/2004
...etc.

I have tried adding selected dates programmactically, in the Calendar1_SelectionChanged event by using
Calendar1.SelectedDates.Add(New Date(Year(Calendar1.Selected),_
Month(calendar1.Selected), _
Day(Calendar1.Selected))

But this only adds the last selected date, it will not retain it's collection.

Thanks for any info....
