How to Add Custom Options To dnsmasq?

[cyboc]

Hi,

I would like to add some custom options to dnsmasq. For example:
srv-host=_ldap._tcp.example.com,ldapserver.example.com,389

There doesn't seem to be a way of adding such options in the DNS forwarder GUI. Would I have to create a custom dnsmasq.conf, like in this post?
