How to use Output Mapper for API response with root array?

I am able to get a JSON object root response to work, like this:
 

{    
    "Items": [
        {
        "name": "root?",
        "thing2": "asdf"
        },
        {
        "name": "root 2?",
        "thing2": "asasdfasddf"
        }
  ]
}

With Mapper like this:

output:
    MAP():
        items: Items
        converter:
            name_output: item.name

Output is this (as expected):

{
  "output": [
    {
      "name_output": "root?"
    },
    {
      "name_output": "root 2?"
    }
  ]
}

Problem is when the input (response object) is an array of objects with no root key to address:

[
    {
      "name": "root?",
      "thing2": "asdf"
    },
    {
      "name": "root 2?",
      "thing2": "asasdfasddf"
    }
]

What would be the equivalent Mapper to use to get the same output as above?
