LinkShiftingTool Edit Template, Multi Connect

I set the node points to allSides.
Two nodes are connected to each other only once.
Is there a way to duplicate this?
How do I apply the following template when LinkingShiftTool is active.

goMake(go.Node, “Spot”, {
// fromSpot: go.Spot.AllSides, toSpot: go.Spot.AllSides,
// fromLinkable: true, toLinkable: true,
// },
// new go.Binding(“location”, “location”),

    //goMake(go.Panel, "Vertical",
    //    goMake(go.Picture, {
    //        maxSize: new go.Size(100, 100),
    //    },
    //        new go.Binding("source", "iconSource")),
    //    goMake(go.TextBlock,
    //        {
    //            textAlign: "center",
    //            font: "bold 11pt Helvetica, Arial, sans-serif",
    //            wrap: go.TextBlock.None,
    //            width: 150,
    //            editable: true
    //        },
    //        new go.Binding("text", "caption"))

I’m sorry, but I really don’t understand what you are trying to do. Could you show several small screenshots showing the behavior that you want, and could you describe how what you have now is doing something different?
