[Radiant] Admin hierarchy vs. URL hierarchy?

[Jay Levitt]

I *think* the answer is "no" but:

Is there an easy way to separate the administrative hierarchy 
(parent/children) from the URL hierarchy, without getting into mod_rewrite 
or Rails routing?

For instance, I'd like to tuck some of the "administrative" pages (about, 
search, RSS) into a folder so they don't dirty up my main Pages display. 
But I still want them to be at http://example.com/search and 
http://example.com/rss.

Are there any extensions that let me specify where the slug is rooted?  This 
is purely out of laziness and aesthetic sensibility; it's not worth me 
hard-coding stuff into routes.
