Add existing relationship to a class on a class diagram

[dbanham@blackberry.com]

Is there a way to select an existing relationship and have that displayed on a class diagram?

I am aware of the "Display All Paths" feature, but when a class has a lot of relationships this feature results in a mess that takes some significant effort to clean up.

And unlike the feature when a new class is added to a class diagram where the typed in name is used to check for existing classes, there is not corresponding feature for class relationships, even when they are named.
