How to add pages in Upfront?

So, I am trying to add a page in upfront, but I can't find where. It is really frustrating. Let me give you an example of our workflow.

User Registers and it gives them a non-upfront theme. Users can then switch to an Upfront theme. We use New Blog Templates to handle the automation of WordPress Pages (3 of them). When the user switches to the Upfront theme, I need the user to edit and attach those pages that are deployed with the multisite. I attached a clip. I need, for example, a Resume page to be able to be added on the home page, and then their respective menus.

Does that make sense? Let me know if you have any questions.

And BTW- Unless I am as blind as a bat, I can't select an Upfront theme from "Select Installed Plugin or Theme".
