Some comments: 1. You don't have to give "anonymous" rights for writing in the dirs. Your Apache task must be able to write.... if you can find, which user and user group it runs, you can give them the write rights.
2. You can copy the template "manually". Note, that since 3.2, the "Copy"-Button in the web interface copies the file AND creates/edit the override.ini file, which will tell the system, when to use the template. I don't know, if just copying the file will be enough for 3.2.
