How to draw a relationship between a property and a class in ArgoUML?

In ArgoUML, I have the ability to put a class Type to any property of a class. For example, I can declare a customer property with a Customer type in the Order class. I can also easily draw a relationship from class to class:

But I can't figure out how to "draw" the link from the customer property to the Customer class. The link is never really connected to the property, but rather to the entire Order class.

I can move the position of the link manually:

But it's never really "locked" to the customer property, and can be moved automatically by the software at any moment.

Is there a way to do this?

You can not have an association in UML which is not connecting the entire two classes. It is not possible to touch the property inside the class. Workarounds are:

• add a note linked to the property
• add an icon to the property which would be designed like an association.

I don't know if this advanced icons customization is available in this free tool but it is in other tools.
