Very true, I forgot about that.
The only ways I can think of doing this are if you KNOW what a characters level will be (and set the new characters starting level to that), did something with variables (I'm not to knowledgeable about these, so it may be a possibility or not) or if you use some sort of script. I may be wrong here, but to my knowledge there aren't any other ways to "transfer" one characters level to another.
