Can the relationship explorer be used to set up a visualization for referenced work instructinos?

We'd like to have some dynamic visualization for our process docs and work instructions by building it into the Structure and then be able to see the relationships in the Relationship Explorer?  Does the Structure Tab, and by extention the Relationship Explorer, only support parent/child relationships or can it represent references/referenced relationships as well?

Is there a better way to get a visual representation of our Manual / Process / Work Instruction relationships?

Thanks for your feedback
