Generate association link automatically

[grand.titus]

Hello everybody

Considering 3 classes belonging to the same package:
-Class1
-Class2 with an attribute "a1" of type Class1
-Class3 with an operation "op1" of type Class1

When these 3 classes are placed on the same class diagram, is it possible to generate automatically:
- an association link from Class2 to Class1 with the target role "a1"
- an association link from Class3 to Class1 with the target role "op1"?

Thanks for your answer
