As it currently stands event missions can be toggled on or off and that is all the control we have over said missions
Which is usually fine, but can sometimes be a bit of an issue when there is multiple overlapping events and you may only want to disable some of them, but not all of them. Also helps with some tasks, as ive found in the past that some events are very common spawn, but others aren't and get buried.
So, a minor suggestion for this is to have an option to enable/disable certain events, rather than them being grouped together in a single setting.
