So I spent some time looking into things this weekend. I have figured out how to change the order of missions within each campaign but nothing beyond that. I will continue to spend some time on it here and there when I am able to!

I have also wanted something like this for FBK. I have coding knowledge and experience but would need to look into what is necessary for these types of changes to know if it is something I am capable of. Will update with that info ASAP.
