Fetching arrays of object via JSON data file in Collection Runner

Hi Team and Beautiful Community

Problem:

I want to fetch from data file (JSON) in the collection Runner an array of object;

Scenario:

I have my collection in the main app here the body with all the fields that are parameterized

{
  "order": {
    "order_date": "{{order_date}}",
    "order_number": "{{order_number}}",
    "reference": "{{reference}}",
    "shipping_method": "{{shipping_method}}",
    "signature_required": {{signature_required}},
    "destination": {
      "name": "{{name}}",
      "phone": "{{phone}}",
      "email": "{{email}}",
      "company": "{{company}}",
	  "building":"{{building}}",
      "street": "{{street}}",
      "suburb": "{{suburb}}",
      "city" : "{{city}}",
      "state": "{{state}}",
      "post_code": "{{post_code}}",
      "country": "{{country}}",
      "delivery_instructions": "{{delivery_instructions}}"
    },
    "items": [
      {
        "description": "My Item",
        "sku": "ItemA",
        "quantity": 1.0,
        "weight": 0.60,
        "value": 25.0
      }
    ]
  }
}

As you can see order.fields are all parameterized and i can fetch a lot of different data for many iterations i like and i can interact dynamically with the underlying API ;
However the array of object/s items is static ;

this below is my data file example (i have just paste one scenarios but i have a files with 50).

[
{        "signature_required": true,
         "reference": "Test1",
         "shipping_method":"express",
         "order_number": "{{randomOrderNumber}}",
         "order_date" : "{{$timestamp}}",
         "name" :  "Company + Building + City",
         "phone" : "00000000",
         "email": "test@test.com",
         "company": "My Company",
         "building": "My Building",
         "street": "20 Wellington Street",
         "suburb": " Bondi",
         "post_code": "2026",
         "state": "NSW",
         "city": "Sydney",
         "country": "Australia",
         "delivery_instructions": "Leave at front-door" 
},
....
....
....
]

IS THERE ANY WAY I CAN ADD AN ARRAY OF 1 OR MORE OBJECTS WITH DIFFERENT VARIABLES IN THE DATA FILE TEMPLATE I HAVE CREATED?

maybe something like this:

[
    {        "signature_required": true,
             "reference": "Test1",
             "shipping_method":"express",
             "order_number": "{{randomOrderNumber}}",
             "order_date" : "{{$timestamp}}",
             "name" :  "Company + Building + City",
             "phone" : "00000000",
             "email": "test@test.com",
             "company": "My Company",
             "building": "My Building",
             "street": "20 Wellington Street",
             "suburb": " Bondi",
             "post_code": "2026",
             "state": "NSW",
             "city": "Sydney",
             "country": "Australia",
             "delivery_instructions": "Leave at front-door" 
"items":[
 {
        "description": "My Item1",
        "sku": "Item1",
        "quantity": 1.0,
        "weight": 0.60,
        "value": 25.0
      },

 {
        "description": "My Item2",
        "sku": "Item2",
        "quantity": 1.0,
        "weight": 0.60,
        "value": 25.0
      },

]

    },
    ....
    ....
    ....
    ]

what would be the code in the request template ? thinking that the request templates will adapt either with 1 item or maybe 2 -3 or more . I am not sure is supported yet.

 "${items}": [
      {
        "description": "{{desc}}",
        "sku": "{{sku}}",
        "quantity": {{qty}},
        "weight": {{wgt}},
        "value": {{value}}
      }
    ]

and what would be the code in the data_file.json ?

thanking you in anticipations for an early reply
