Dynamic page route parts in Blazor WASM app

In my Blazor app I want to have default pages such as:

/Home/Info

With specific typical functionality.

However, I also want to have dynamic pages (perhaps generated from database content that will change over the lifetime of the app). These will also ideally be accessed by a singleword, such as:

/Custom1/Custom2

How can I use page routing so that code decides if the route is one of the valid dynamic pages (such as the Custom pages) whilst also retaining use of the default (static) pages?
