This is the opposite of how most ITSPs and deployments expect things to 
operate, which is why you're seeing the behavior you are. It's not 
written to behave like this. Your best bet is to do as you've mentioned 
and manually manipulate things. This is also, I think, the first time 
I've ever heard of a company wanting it to behave precisely like that.
