Google Analytics Goals with Sub-domains

Question

We are releasing a paid web application. We have Google Analytics and want to set up conversion goals to see who signs up on the various accounts. I.e. what demographic is buying the highest plan, etc. The problem is that Google Analytics assumes that it is tracking a single domain, and our application operates on several sub-domains (signup.ourapp.com, accounts.ourapp.com, user-subdomain.ourapp.com).

So my question is: is there a way to use wild-card domains with Google Analytics, specifically when creating conversion goals? Our goals would look something like this:

1. http://www.ourapp.com/signup
2. http://accounts.ourapp.com/signup/[plan-name] (This will be different for each goal)
3. http://[user-account].ourapp.com/dashboard (Goal)

The Google Analytics Goal Settings page asks you to put in the paths of the goals, not the full URLs (i.e. /signup not www.ourapp.com/signup). Also, I am not sure if you can even put the Google Analytics JavaScript code on multiple domains and have it track it properly.

Does anyone have any input on this?
