Idea Summary
In this new DA (24.1) you can set one prompt only. This limits the Q&A to progress in a customized way.

Use Case
I'll take the Highschool workshop as an example. 

In this app you can set the school context after selecting the school. In a more realistic scenario you may not know the context yet. E.g. when asking about an order the Q&A would be more like:

You: What is the status of my order?

AI: (if the order number is not known) What is your order number?

You: It's 10012234

AI: (before you ask the AI, you set the prompt with the relevant info about the order using a query, like it's done in the Highschool demo for a particular school) Your order is ready for shipping.

Preferred Solution (Optional)
An option to process the AI response and set a new prompt for the next AI call.

Alternative: if the chat is made available as a region type template (or something like that) you can create this conversation yourself using APEX_AI.
On mylearn.oracle.com there are some videos about APEX and AI  that show a custom LLM Conversation region type.
