Folder structure for controllers

[eluser]pan69[/eluser]
Hi guys. I'm working a somewhat largish site and I really need to subdivide my controllers folder into sub-directories. If I don't I get a whole bunch of incoherent files sitting in one folder which is going to do my head in.

So e.g., In the 'Settings' section of my site I have a whole bunch options. I'd like to arrange the controllers for all these options in the 'settings' sub-folder of the controllers folder. However, out of the box this is going to clash. When I call ~/settings/users I actually want to call the Users controller in the controllers/settings folder.

Is this possible?

Thanks,
Luke
