Get outer json key value into very json in the nested json array using JOLT

Question

I have a JSON like this

{
  "id": "1234",
  "name": "something",
  "list": [
    {
      "A": "Something"
    },
    {
      "B": "Something1"
    }
  ]
}

What I would like is to do is add id and name to both the JSON's present inside list I've gone through a couple of questions and I couldn't find anywhere where somebody had done this.

I believe the following Shift spec will work:

{
    "id|name": "&",
    "list": {
      "*": {
        "@(2,id)": "&2.[&1].id",
        "@(2,name)": "&2.[&1].name",
        "*": "&2.[&1].&"
      }
    }
}

With your sample data, the output produced was:

{
    "id": "1234",
    "name": "something",
    "list": [{
        "id": "1234",
        "name": "something",
        "A": "Something"
    }, {
        "id": "1234",
        "name": "something",
        "B": "Something1"
    }]
}
