multiple relationship support

I want to be able to show multiple parent relationship. It does not necessarily mean that every element of the tree has multiple parents, but it would be an interesting feature to add secondary connections to the tree, i.e. Employee X has a functional boos Y and an administrative boss Z

           N
         /   \
       Z      Y
     /       /
    X-------

I wanted to use it to render a directed graph, which would require multiple parents for nodes. I understand that it would complicate layout logic as you need to attempt to minimize overlap etc., so this may not actually be in the scope of the library. A beer would definitely be in order if this functionality was introduced.

Is this still the case? Is there any plan to implement this functionality?
