Open up specific URL in Auth Controlled Folder

I have basic HTTP auth configured to a specific Location in my Apache config like:

<Location /system>
  AuthType Basic
  AuthName "Password Required"
  AuthUserFile /to/passwd/file
  Require valid-user
  Order allow,deny
  Allow from xxx
  Allow from xxx
  Satisfy Any
</Location>

with /system aliasing a folder which goes to a path /system.

Now I have a URL in this /system path of /system/user/synchro which I need to be public to everyone. It should be noted that the destination of the path is not a physical file but rather a rewritten URL.

Is there a way to nest a Location (or something) to be able to open up this one path but keep the rest locked down?
