How to pass information to child items with node-object-mapper

[MateusArenas]

I really like this JavaScript library, and I would love for it to support what I need for a project I'm working on. Could you help me with this, @matmar10 , @wankdanker , @irnc , @weshardee , @kevinvn1709 ?

I would like to dynamically pass a value to the child items below.

{
  "pedido": {
    "volumes": [
      {
        "itens": [
          {
            "etiqueta": "abc",
            "cod_item": 1
          },
          {
            // The value didn't appear here...
            "cod_item": 5
          },
          {
            // The value didn't appear here...
            "cod_item": 6
          }
        ]
      },
      {
        "itens": [
          {
            "etiqueta": "zpl",
            "cod_item": 3
          }
        ]
      }
    ]
  }
}

var mapping = {
  "pedido.volumes[].registro": [
    "pedido.volumes[].itens[].etiqueta"
  ],
  "pedido.volumes[].itens[].codigo": [
    "pedido.volumes[].itens[].cod_item"
  ]
};

const originalData = { 
  pedido: {
    volumes: [
      {
        registro: 'abc',
        itens: [
          { codigo: 1 },
          { codigo: 5 },
          { codigo: 6 }
        ]
      },
      {
        registro: 'zpl',
        itens: [
          { codigo: 3 }
        ]
      }
    ]
  }
};

const mappedData = objectMapper(originalData, mapping);
