Virtualmin and name based hosting


I am having a problem with virtualmin and my named based hosting.

I want to use name based virtual hosts and also set a specific ip address in my host file (DNS). virtualmin does not seem to allow this.

therefore everytime I setup a new domain virtualmin breaks my apache config file and I have to manualy edit it. As virtualmin sets it up for ip based hosting, ie. instead of *:80.

is there a setting i have missed?
