You have a lot of experience building GoJS apps, so I would think this would be easy for you to implement. Things are pretty busy right now, so I’m not sure when I’ll get a chance to implement this.

I assume you already know about using two arrowheads on the links.

    myDiagram.nodeTemplate =
      $(go.Node, "Auto",
        { resizable: true, fromSpot: go.Spot.AllSides, toSpot: go.Spot.AllSides },
        new go.Binding("position", "position", go.Point.parse).makeTwoWay(go.Point.stringify),
        new go.Binding("desiredSize", "size", go.Size.parse).makeTwoWay(go.Size.stringify),
        $(go.Shape, "RoundedRectangle",
          { parameter1: 2, fill: "white", stroke: "gray", spot1: new go.Spot(0, 0, 1, 1), spot2: new go.Spot(1, 1, -1, 0) }),
        $(go.Panel, "Vertical",
          { alignment: go.Spot.Top, stretch: go.GraphObject.Horizontal },
          $(go.Panel, "Table",
            { background: "lightblue", stretch: go.GraphObject.Horizontal },
            $("TreeExpanderButton", { alignment: go.Spot.Left }),
            $("Button", { alignment: go.Spot.Right, width: 13.5, height: 13.5 })  // ...
            { margin: 3, editable: true },
            new go.Binding("text").makeTwoWay())

    myDiagram.linkTemplate =
        { routing: go.Link.Orthogonal, corner: 3, toShortLength: 2 },
        $(go.Shape, { stroke: "gray", strokeWidth: 1.5 }),
          { segmentIndex: 1, segmentOffset: new go.Point(0, 10), alignmentFocus: go.Spot.Left },
          new go.Binding('text', 'label').makeTwoWay()),
        $(go.Shape, { fromArrow: "Circle", fill: "gray", strokeWidth: 0 }),
        $(go.Shape, { toArrow: 'Triangle', fill: "gray", strokeWidth: 0 })
