Two main outlets, each with routes handling dynamic segments

Is there a commonly accepted solution to a problem I'm currently facing?

Lets say you have an app that needs to have a set of quite normal routes, some with dynamic segments. But also another outlet in the app, lets say a sidebar for example, that can be opened from any one of the main apps routes. This sidebar also has its own routing structure, with some routes requiring dynamic segments too.

How could one implement routes for a sidebar that could be opened from any other normal route in the application?
