Hi, is there any way to acomplish the blue line in the attachment?

I'm evaluating the controls for a project i've been assigned.

I need to make diagrams but i have to use a very strict symbology when connecting 2 shapes, there are different kind of "lines" i have to use depending on some conditions.

E.g. One line with a "messed up" line over it to indicate the relation between the two objects is complex.

Thanks in advance.
