Hierarchical layout, edge grouping only grouping before nodes: Is there a way to make it group on both sides?

Question

I'm using hierarchical layout with edge grouping set to automatic.  Edges above each node group perfectly, but after each node, they are not grouped causing a lot of edge crossing and a very confusing diagram.  Is there any way to make them group on both sides.  Its important for the diagram that the hiearchy be preserved and that edges enter at N and exit at S on each node.

Thank you!

The hierarchical layout setting "Automatic Edge Grouping" takes care to include each edge in either a source or a target group, but never both. If you want to have edges that are both source and target grouped, disable "Automatic Edge Grouping" and specify explicit edge groups using "Tools" -> "Constraints" -> "Edge Grouping" instead.
