[2022] Side Quests in Coop Game/New features

Hello Anno 1800 Team,
Before this post begins, I just want to say that this game is amazing and I really love it. Congratulations for all this work !!!
I like to play the game in coop mode, just one player faction against AI, but for the game it's a multiplayer game so every side quests are disactivated and it's shame because these quests are really good. So I have a proposition, the idea is just to create a switch for coop mode when you create a multiplayer game this will allow just one player faction and every side quests will be alvailable so the game will be categorised as coop game and not multiplayer game. I don't know if it's difficult to implement in the current game but I think it's a feature that can be really good in the game because coop is really fun in this game because there is so much things to monitor.
Sorry for this bad english,
Thanks if you can manage to do this but if not I will never to stop to play this game.
