Split router while using verified routes

trying to split the large router file

this is some simple representation of my router

# part of MyAppWeb.Router.ex
  scope "/shop/:shop_id" do
    scope "/users" do
      live "/"
      live "/:user_id"
      # large sub routes
      ...
    end

    scope "/items" do
      live "/"
      live "/:item_id"
      # large sub routes
      ...
    end
  end

I searched, and it seems there are 3 options for splitting router.

1. using “forward”

not possible, as it does not allow to forward to route with dynamic segment

== Compilation error in file lib/my_app_web/router.ex ==
** (ArgumentError) dynamic segment "/shop/:shop_id/users" not allowed when forwarding. Use a static path instead

2. using “match”

not able to catch error with verified routes

scope "/shop/:shop_id" do
  match :*, "/users/*path", MyAppWeb.UserRouter, :any
  match :*, "/items/*path", MyAppWeb.ItemRouter, :any
end

with this method invalid path like a “/shop/1234/users/1234/no-exist-path” was not caught by the verified routes.

3. plug routers to Endpoint.ex

not sure if it would work. how to declare verified routes on this setting?

 # part of Endpoint.ex
defmodule MyAppWeb.Endpoint do
...
plug MyAppWeb.Router
plug MyAppWeb.UserRouter
plug MyAppWeb.ItemRouter
end

code above is not working. it seems the Router return NoRouteError before UserRouter.
there is a solution for this(Using multiple routers in Phoenix - #3 by alexgleason)
but still not sure how deal with the VerifiedRoutes.
i need to fix code below to properly handle multiple router.

# part of MyAppWeb.ex
use Phoenix.VerifiedRoutes,
      endpoint: MyAppWeb.Endpoint,
      router: [MyAppWeb.Router, MyAppWeb.UserRouter], # array of router is not valid input
      statics: MyAppWeb.static_paths()

please help!
