I have made a simple system to allow/forbid jobs via scripting, currently i am using it for crime mangement / micro, but i plan to remove the current amenity management and replace it with the new scripted system. It would then be possible for people to mod the system in order to expand it with different settings. For example, you could then script 3 different toggleable settings for low/medium/high amenity target. But for the non-modded vanilla version of the game I think it may be a bit much to provide 3 different amenity settings
