Sub child pages and ion content

I have an app I am converting to run with ionic(its already in angular) but I built it where there is a master page within child pages. And some of those child pages are master pages for 1 more level down of child pages.

How do a create a sub master page in ionic. Or is this not how Ionic is structured and there is a better way to go about this? Below is an example of the routing I am using so you can see how the sub folders come into affect.

In other words I am trying to create a multi step form!
