Is there a way to force file permissions by directory (and subdirectories under it)?

For example, the user's default umask value is 022 but I want it to be 002 in certain directories.

I have cronjobs like this to regularly give group read permissions (and x for dirs) on /some/dir and all it's subdirs:

/usr/bin/find /some/dir -xdev ! -perm -g+r -print -exec chmod g+r {} +

/usr/bin/find /some/dir -xdev -type d ! -perm -g+x -print -exec chmod g+x {} +
