Is there an Angular counterpart to secondary routes in Ionic 3?

all!

We are creating an application that will run both a web page and an application. So far we have used ionic navigation, but for the next production step, the flow was completely rebuilt. Most views are still fine, but the screenshot has a few pages with secondary routes and breadcrumbs:

In angular, such routes are not a problem, but what about ionic routes? If it were just the Deeplinks mobile app it would be more than enough, but it doesn't seem to support secondary routes and that's important for the webpage. Does anyone have any ideas on how to get this all to work?

We are using Ionic 3.0.1 and angular 4 so far trying to keep the build of the latest technology. Feel free to ask any questions.

Any help or thoughts are appreciated!
