Symfony 3 Bulk and Nested Routes

I am currently working on a Symfony project with a lot of namespaces and Bundles. Many of them use the same basic route:

# /app/config/routing.yml
something:
  resource: "@SomethingBundle/Controller/"
  prefix:   /admin/something
  type:     annotation

      

        
        
        
      

    

Now at least 10 other packages use the prefix /admin

, so I was wondering if there is a way to group and embed them in them? I imagine something like this (pseudocode):

admin:
  prefix: /admin
  nested_resources:
    - something:
        resource: "@SomethingBundle/Controller/"
        prefix:   /something
        type:     annotation
    ...
