Is there some way to add a whole list of subcases at once?

I'm using Fogbugz for managing the creation of Web sites. Each time we sign up a new client, I want to be able to create a Case for the site, plus a bunch of subcases for the specific tasks involved in creating the site ... the list of subcases is going to be mostly the same each time. I'd like to be able to simply copy a list of case names into the Subcases box in the parent case's Edit page, but that currently doesn't work.

So, either I'm missing something here, and there is a way to do it, or ... can we have this feature?
