Gathering information with slots multiple times

Currently the slots are prompted once like the pizzeria example. You can order one pizza. But what if the customer wants more pizzas in one order?

My idea is a slot option "Prompt for multiple" like in the attached picture.

If activated the first slot will ask for the amount of data to ask for and create a JSONArray in context.

"context": {

"slot_data": "<? new JSONArray() ?>

}

If all slots are filled the context data will be appended as an JSONObject to the slot_data:
$slot_data.append({"slot1": $slot1, "slot2": $slot2, ...})

If an amount is set all slots will be prompted again until $slot_data.size() == amount ("Now choose your next pizza").

If no amount is set and all slots are filled, the customer will be asked if he/she wants to add more data ("Do you want to order one more pizza?").
If $slot_data.size() has reached the amount or the customer don't want add more data, the dialog will continue in the next node.

Developers could set a minimum and maximum to the $slot_data.size() with a response if the amount is not in the limits.

If Watson Assistant would support looping through dynamic arrays, the slot_data could be processed further in the dialog. I already created an request for that: https://ibm-data-and-ai.ideas.aha.io/ideas/ASSISTANT-I-218

This feature gives new opportunities to ask your customers for multiple data, like adding more data to orders, peoples contact info and many more.
