UMLR — Link notation for stereotype property value

It would be very useful if a notation was defined to allow a stereotype instance property value which references another instance in the model to be shown as a link on a diagram.

For example, a stereotype Foo could have a property Bar of type Foo (in order that one Foo can reference another Foo). On a diagram showing two instances of Foo, you could then add and show a link between them labelled Bar rather than only being allowed to use a compartment or callout note.

This would be useful to many profiles, but I couldn't find an existing issue which covered it.
