I have not find any attempt to start yet, so the question is - is it possible to add at path behind the output of a custom post type?

This means: I have a custom post type "movies" and fill it with several categories and other attributes/ratings/whatever.

Their Path will be: www.test/movies/themovie1, .../themovie2, ... and so on

What I need to add is an automatically generated page that takes input from both movies and will generate behind EACH movie, just as it was a child element of "movies" in the hierarchie:

www.test/movies/themovie1/alternatives

and even "better": www.test/movies/themovie1/vs/themovie2 and vice versa: www.test/movies/themovie2/vs/themovie1

Those have to be created automatically - I plan to create JSON files as a source for them as all the possible combinations being written into the database via insert_post would kill the database with millions of pages - I already know the architecture I need, issue is: can I create a single-movies.php that creates those sub-folders? (Possible idea: using a GET Query and have it transformed instead of ?vs=xyz?)
