title: Jolt Transformation: How to shift some values into each map in list
body: <p>I have been working on Jolt transformation from yesterday and unable to find a solution to achieve following output.<br>
  I would like to insert "year","month","day" into each map (dictionary) of "records" list. </p>
  
  <p><strong>Input</strong> <br></p>
  
  <pre><code>[{"root":
     {"body":
      {"year":2019,
       "month":8,
       "day":9,
       "records":[
         {"user":"a",
          "item":"x",
          "price":300,
          "count":1},
         {"user":"b",
          "item":"y",
          "price":100,
          "count":3}]
       }
     }
  }]
  </code></pre>
  
  <p><strong>Desired Output</strong></p>
  
  <pre><code>[{"user":"a",
    "item":"x",
    "price":300,
    "count":1,
    "year":2019,
    "month":8,
    "day":9},
    {"user":"b",
     "item":"y",
     "price":100,
     "count":3,
     "year":2019,
     "month":8,
     "day":9}
  ]
  </code></pre>
  
  <p>I could insert value of "year", "month","day" into outside of each map as list like {"record":[[2019,8,9],{map1},{map2}]}, but this is not what I want.<br></p>
  
  <p>I appreciate for any help or advice. And thank you in advance.</p>
