I'm outside my area of expertise here, but I have a feeling that what
you are trying to do needs dynamic-DNS support in the DNS server. Ie the
ability for client to add/alter DNS records. Dnsmasq doesn't provide
that facility. Adding it would be a major undertaking.

Use server=/<domain>/<server> to forward the domain in question to a DNS
server which supports dynamic-DNS. dnsmasq should have no problems
_forwarding_ DNS-update requests, even if it cannot act on them.
