I'm trying to find the best way to implement multiple themes. I'm actually doing subdomains within the instance (with the idea of using Domain Mapper or something of the like). The subdomains have a different theme. I have the theme itself working fine, but is there no way to set page defaults for the second theme?? I can't seem to figure this out. If not, that is a HUGE drawback for what I need to do as telling the users to add a nav block to every pages is not going to go over well.

Any help/suggestions out there?
