HMVC and controllers

[eluser]MgM Web[/eluser]
Ok, so when im using modules I am supposed to add new controllers inside the modules folder and not use the controllers folder? This is my structure at the moment.

Controllers:
application/controllers/welcome.php

Modules:
application/modules/menu_module/controllers/menu_module.php
application/modules/news_module/controllers/news_module.php

The menu and news are partial views that I use inside my view in the frontpage (welcome.php).
Next I am going to create a subpage "http://www.mysite.com/subpage". Normally I would create a new cotroller like this:

application/controllers/subpage.php

But this is not working, am I supposed to use the modules folder like this:

application/modules/subpage/controllers/subpage.php
