class ActionDispatch::Routing::Mapper
  def draw(routes_name)
    instance_eval(File.read(Rails.root.join("config/routes/#{routes_name}.rb")))
  end
end

BCX::Application.routes.draw do
  draw :api
  draw :account
  draw :session
  draw :people_and_groups
  draw :projects
  draw :calendars
  draw :legacy_slugs
  draw :ensembles_and_buckets
  draw :globals
  draw :monitoring
  draw :mail_attachments
  draw :message_preview
  draw :misc

  root to: 'projects#index'
end

How can I use concern with this conven?
https://guides.rubyonrails.org/routing.html#routing-concerns

concern :commentable do
  resources :comments
end
resources :messages, concerns: :commentable

can I do this?

draw :api, concerns: :commentable

or there another way?
