UML Static Diagram - Resize Connectors

[EulerOperator]

Visio 2003 SP 2

I am creating UML Static Class diagrams. I want to resize or reposition the
cardinality indicators at the ends of a composite or associative connector.
Tried everything possible, but can't seem to do it.

In particular, I'd like to change the relative position of the cardinality
indicator for ALL connectors in a diagram. I can rotate them, but not
reposition.

Thank You.

My idea is to use cellchanged or formulacganged events.
