I do not know exactly what you are referring to but there's ways you could probably set something like this up.
If the response ends in a question it will listen again. so you can engineer this in the prompt to get it to ask "is there anything else?" or similar after responses unless you say "that is all" or similar.
another way is to automate off the assist pipeline finishing and then checking to see if "conversational mode" is on (toggle helper maybe?) and then if it is call assist_satellite.start_conversation with a tiny short blank media file or something so it starts listening quickly.
You could also do this from within ESPHome firmware instead of HA automation if your using an ESPHome satellite.
Whatever the case you might want to use 2 separate wake words for different pipelines/modes. e.g.
"okay nabu, whats the weather" - "rainy"
vs
"hey jarvis, whats the weather" - "rainy, is there anything else"
so you can decide if you want back and forth or not.
