Story/Scenario

Hello! I've been a Xoulian for a while now, I was looking for an AI platform just like this! The features that this website provides is honestly insane, I'm most impressed about the UI interface, it has the same similar feeling. One major downside that I was REALLY looking forward to was the Story/Scenario setting. However, the system that it provides is somewhat weird to configure. I don't think this is me only, but I want a system that is if not the EXACT same to Xoul's. Xoul's protocol as follows: You choose one or more characters to talk to, then choose one premade Scenario by a user. I'm not requesting an overwritten action, I am simply requesting a possible integration, or another option to change the story setting
