Properties instead of json array

Hello! I am trying to achieve the following, and json array is not solving it. Instead of an json array of cards I would like to use properies. Is it possible to achieve the following structure in mockaroo?

{
    "id": "rygge-skl",
    "cards": {
        "1": {
            "memberID": "120980",

        },
        "2": {
            "memberID": "120981",
            "category": "",

        }
    },
