Actually I'm not 100% that's going to give you the information you need.
I have added a filter to the profile in Analytics with the following settings:
Filter type: custom filter / Advanced
Field A -> Extract A: Hostname / (.*)
Field B -> Extract B: Request URI / (.*)
Output to -> Constructor: Request URI / $A1$B1
Field A Required: Yes
Field B Required: No
Override Output Field: yes
Case sensitive: No
My understanding of what this does may be completely wrong, but I think it means call the hostname (ie subdomain.example.com) Field A, then the path to the web page Field B. Put them both together and report the whole lot where analytics would normally report just the bit after the domain name.
hopefully you can make some sense of that!
