Sorry this isn't going to happen. This was already Denied Here not too long ago. Make sure to search your request before posting please, and if your request is a toggle feature chances are it won't get added. The feature is supposed to benefit everyone and having the ability to toggle something means that not everyone is going to use it or like this.
Don't forget to read the Forum Guidelines before posting thanks!
