Feed JSON data into a WhatsApp Flows

At the moment, it's possible to pre-fill data in some components of a WA Flows (e.g. a string or number) using the dynamic int value. Unfortunately it's not possible to feed a JSON object which can be used to populate components like dropdown which limits the usability of the Flows. For example, you are fetching a list of products from the API and want to use them within the Flows. Some bot builder have this option to "feed" the data which can then be used within the editor (see screenshots attached).
