Please look into the function to be able to change a sent message if something was left out or a spelling mistake slipped in without having to "intercept" it but then having to redo everything from scratch. Why can't a message that was intercepted be changed and sent out again?

Why isn't there a function to totally delete a message? When it is intercepted it stills shows on this side for the admin unlike with the communicator where it could be totally deleted.
