Set hardlinked audiobook folder permissions to 775 or 755

[ckozak]

I have Shelfmark configured to create a folder per audiobook for ABS structure, but the folder has rwxr-xr-x permission, what results in my ABS not having permission to operate on it, as it runs under a different user, but in the same group. So I have to run "chmod 775 -R folder" or "chmod g+w -R folder" for every such folder to give it permission to operate on the folder, as I have ABS store metadata in the folder.

Is there a way to configure Shelfmark to create the folder with different permissions? Or it need to be a feature request?
