Set pages to display under subdomain?

Hello I have my site set up and everything seems to work with theme switching and the sub domains for posts. However I want to set my sub domains each to a separate static landing page as well as add pages to that sub domain.

For instance i have 2 shows, Show 1 & show 2. Each has its own category set up as a sub domain so all posts will show up under the sub domain. However I would essentially like to set the homepage for each sub domain as a static page as you would with the parent domain in the reading section of settings.

Example
sitename.com -> Main static homepage
show1.sitename.com -> Static homepage show1
show2.sitename.com -> Static homepage show1

Now i am not sure if it is just something i am missing along the way but i cant for the life of me figure out how to do this. I would also require the ability to continue to add new pages, main menu’s and more to each individual sub domain.

Is this possible or is this out of the scope of this plugin?
