Changing file owner?

Permalink
I've upgraded a site to 5.3 and wanted to use the cool new file set permission stuff.

The user shouldn't have access to all the "layout files" which is why I wanted to disable the access to the "admin files".

This work fine but unfortunately all the files are owned by the admin. I reuploaded the file again using the user account, delete the old file and changed all the links on the pages..

This works, but isn't there a more comfortable way?
