Changing Values by Grouping and Dragging

[AndThat]

Using OL 2003

Is there any way to change the subject line of a bunch of tasks or
appointments at the same time?

I used to be able to do this by grouping the items by subject and then
dragging the highlited items to a different group but it won't work now with
OL2003

Same thing for changing the Contacts associated with a Task or Appointment.

Thanks
