Genogram: relative positioning after sorting

I've tried multiple ways to enforce ordering in complex genograms (e.g. presorting nodes / marriages), and the only solution I've found that works is to delete and re-add vertexes in the sorted order before the assignLayers step:

    var allv = new go.Set().addAll(net.vertexes);
    var vertexList = new go.List();
    allv.each(function(mv) {
      if (mv.node == null) return;
      vertexList.add(mv);
      net.deleteVertex(mv);
    });
    vertexList.sort(familySort);
    vertexList.each(function(vertex){
      net.addVertex(vertex);
    });

While the relative ordering of the nodes are correct, this seems to negate the optimal positioning of the nodes w.r.t optimal link lengths. Is there a way to "hint" positioning of nodes in a way to retain order? Example shows how the ordering is correct, but nodes become left aligned.
