Is there a way to limit listDirectory() ?

I'm using atmos-php and there is a cloud directory which has the contents of files uploaded by Atmos Geodrive. I then am trying to list the contents via a php script on a webpage, but the file list is too long (I am watching the TCP traffic and the XML is being returned but it will probably take forever to list the files).

Considering there is the potential for (and probably are) thousands of files, I'd like to paginate the directory listing using atmos-php for the PHP script.

So, is there some sort of helper or way to paginate the directory listing?

Thanks.
