We want sending to specific or tailored flow be in a single GPT Action, I use default reply in most of my GPT integration, this gives me flexibility to use advanced flow manipulation. It's really hard to use conditions with multiple GPT actions to provide instructions and direct them to a flow or even using the Triggers, if there would only a feature in instructions, let's say using ##CONDITION within prompt, and send them to a Step ID or a flow ID, then it would provide more advanced and powerful flows.
