How to use So-CSS on non-default main page of site?

Hi,
So-css is working great for me!

EXCEPT – it’s stuck on looking at elements on the main page of the site.

Is there a way to navigate to another page within so-css?

My work around had been to change the default page, but now I need help on a custom post type which isn’t allowed as the default page… so a bit stuck.
Thank you for your help!
Thanks for such an awesome plugin!
