WebDav & File permissions

Is there anyway to have files and folders created inside of a WebDav mount point be readable by my user on the webserver?

I have a PHP script that creates pages based on the contents of a folder. I thought I would make my life simple and set this content folder for webdav access, I edit the files on my machine easier this way.

The problem is that existing files and folders are setup so the are readable by my user account, but new files are not. New files are set to 640, while existing files/folders are 644. The owner and group is dhapache regardless.

So is there a way to have webdav created files/folder be 644 instead of 640?
