Allow setting A/AAAA on a per-subdomain basis

[PythonCoderAS]

Is your feature request related to a problem? Please describe. I have SSH open on IPv6 only, but I have HTTPS open on IPv4 and IPv6.

Describe the solution you'd like I want to make two subdomains, one with an A/AAAA record for HTTPS, and a second subdomain just for SSH that is IPv6 only.

Describe alternatives you've considered I could run two instances, or just deal with both subdomains having both an A/AAAA record.
