Put a value as a JSON Key

Hi everyone,

In Anypoint Studio, i would like to put a value as a key JSON. by default, i couldn't map the key.

input:
{
	"total_rows": 7,
	"offset": 0,
	"rows": [{
		"id": "0dd206faa4e454bbbf8133ab8c0a87bc",
		"key": "0dd206faa4e454bbbf8133ab8c0a87bc",
		"doc": {
			"_id": "0dd206faa4e454bbbf8133ab8c0a87bc",
			"_rev": "1-c140584e7b8a7841b6a1b85baa77c82d",
			"recordType": "product",
			"productID": "CK234324",
			"productName": "Branded Air Fly High Quality Sneakers",
			"category": "Enterprise",
			"SKU": "CKS100",
			"price": 100,
			"inventory": 35868
		}
	}]
}
 
expected Output:
[{
		"CK234324": {
			"_id": "0dd206faa4e454bbbf8133ab8c0a87bc",
			"_rev": "1-c140584e7b8a7841b6a1b85baa77c82d",
			"recordType": "product",
			"productID": "CK234324",
			"productName": "Branded Air Fly High Quality Sneakers",
			"category": "Enterprise",
			"SKU": "CKS100",
			"price": 100,
			"inventory": 35868
		}
	}]

Here an example if it's not clear.

Thanks All.
