Message stereotype in Sequence Diagram   

Hi,

I'm using Visio 2002 pro, and I have a problem with Sequence Diagram.
I'd like to use stereotype <<create>> and <<destroy>> for messages to
show the situation, when one object creates/destroys another. In
UML/Stereotype menu are there that stereotypes defined with base class
Event, but when I drop the Message onto Sequence Diagram, the field
Stereotype (properties page of the Message) is disabled. Why?

How can I solve this problem?
