Add DNS records without preventing automatic generation
I have my domain sign my emails with DKIM, using the host name as a selector, but I can also use an external SMTP server for some things, which has given me a public key to add to DNS. I guess in this case, I want to be able to add records to the DNS for the domain, but if I edit the DNS file, all other records will stop being updated. It would be good if there could be a different file for additional records so that the automatic file would still match its checksum.
