[Treantjs]: Grouping same node included by different parent - is it possible?

[egor-progger]

Description from treantjs issue

This is my tree:

Is it possible to not repeat the treantAss1 node, but rather make it appear once and be referenced directly from: treantAss2 and treantMap2 nodes?

This is JS config:

var treantAss1 = {
  "text": {
    "number": "treantAss1"
  },
  "children": [
    {
      "text": {
        "number": "treantMap1"
      },
      "children": [
        {
          "text": {
            "number": "treantPN1"
          }
        }
      ]
    },
    {
      "text": {
        "number": "treantPN2"
      }
    }
  ]
};

var nodeStructure =
{
  "text": {
    "number": "treantAss3"
  },
  "children": [
    {
      "text": {
        "number": "treantAss2"
      },
      "children": [
        {
          "text": {
            "number": "treantPN3"
          }
        },
        treantAss1
      ]
    },
    {
      "text": {
        "number": "treantMap2"
      },
      "children": [
        treantAss1
      ]
    }
  ]
};


var chart_config = {
    chart: {
        rootOrientation: "WEST",
        container: "#basic-example",

      animateOnInit: true,

        node: {
            collapsable: true
        },
        animation: {
            nodeAnimation: "easeOutBounce",
            nodeSpeed: 700,
            connectorsAnimation: "bounce",
            connectorsSpeed: 700
        }
    },
    nodeStructure: nodeStructure
};
