You'd certainly need a whole additional rule syntax for something like that: which files is sudo allowed to write to; does it append, overwrite or both (both should certainly be options); what happens when the write fails (the original file must be left untouched at all costs) and so on.  Of course tee / cat are unlikely to do that either: almost certainly the answer is a tool which does, which can then just be used in ordinary sudo rules: 'echo ... | sudo fwrite -a /etc/config_file'
