.set() method should add the key value if its not present

[akanshSirohi]

I have this JSON with me

[
    {
      "msg": "hello",
      "_uuid": "1483f2e6-1241-4e84-9fbf-503ce5ea64df"
    },
    {
      "msg": "hello",
      "child": {
        "timestamp": "any_timestamp"
      },
      "_uuid": "dbe96d86-4542-4bbd-b64e-f31d69fa735b"
    }
]

I am executing this code to update the timestamp value

DocumentContext collections_doc = JsonPath.parse(json_data).set("$[?(@.msg == 'hi')].child.timestamp","new_timestamp");

Its just updating the first child.timestamp, is there any solution so that if object don't have any key, then it will be created.
