The title isn't very clear sorry about that. :) Here's my problem:

I have a "List" page which has a drop down filled with the names of all the child pages. The child pages can be all sorts of different pages who all have their own templates, standard pages etc.

Assume the following structure

Releases

2014

2013

2012

When a user then selects an item in the drop down, specific data of that selected page is displayed on the "List" page. Easy enough.

However, I do not want to use a query string like page=2014 or something similar.
Instead what I want to do is /Releases/2014.

So, if I have a page which is a child of the "List" page, the "List" page should be rendered instead (as if the Release page was requested) instead of the requested child page and display the data of the requested child page, just as if a query string would've been used on the "List" page.

/Releases/2014
should produce the same result as
/Releases/?page=2014

I've tried to solve this using partial routing, but it won't trigger unless the page doesn't exist. Is there a way to "prioritize" my partial routing or am I going about this all wrong?
