You can edit what it replied of course (and then hope it builds off of that and keeps that specific vibe going, which always works in the playground) but damn, they locked it down tight. 😅

Even when you edit the primer/setup into something crazy (you are a grumpy or deranged or whatever assistant) and change some things it said into something crazy, it overrides the custom mood you set for it and goes right back to its ever serious ChatGPT mode. Even sometimes apologizing for saying something out of character (and by that it means the thing you 'made it say' by editing, so it believes it said that)
