Well, sorry to brake this fantasy bubble but the only reason prompts works in Solasta is because it's a singleplayer game only.
It's one thing to have one player controling the party but it's totally different beast to have multiple people with their own character have reactions on the same event in the game. All sorts of conflicts and errors can happen.
IF they remove multiplayer, sure we can have prompts np. But untill that happens no go.
