Two scopes with the same :as in rails

I have some rails 3 routes that worked perfectly, for versioning an API with different module:

Rails.application.routes.draw do
  scope module: :v2, constraints: Constraints::ApiVersion.new(versions: [2, 2.1], default: false) do
    scope 'feedback/:id' do
      get 'summary', controller:'summary', action: 'summary', as: 'response_summary'
    end
  end

  scope module: :v1, constraints: Constraints::ApiVersion.new(versions: 1, default: true) do
    scope 'feedback/:id' do
      get 'summary', controller:'summary', action: 'summary', as: 'response_summary'
    end
  end
end

But now in rails 5, I get this error:

Invalid route name, already in use: 'response_summary' (ArgumentError) You may have defined two routes with the same name using the :as option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with resources as explained here: http://guides.rubyonrails.org/routing.html#restricting-the-routes-created

Is there anyway to keep the :as the same in Rails 5?
