Transform complex JSON structures from CosmosDB to SQL DB with Azure Data Factory

The current scenarios allow you to convert Arrays or Complex Types (JSON) into single columns (as mentioned in this post) or convert columns into JSON.  However, is there a way to convert the JSON back to the string representation for storage into a SQL Column?

Example:

Source:

{
    "id": 1234,
    "data": {
        "name": "Acme, Inc.",
        "address": {
            "city": "Seattle",
            "state": "WA",
            "zip": "98195"
        }
    },
    "additionalData": {
        "color": "red",
        "shape": "square",
        "number": 4
    }
}

In this case, I don't want to store color, shape, and number as distinct columns, but as text: { "color": "red", "shape": "square", "number": 4 }.

Is this possible currently, or something coming in the future?
