Custom Domain for Resolution

Currently, using the standard dns.nextdns.io domain for DoH/DoT I get a high rate of blocking on public networks. This is probably because it is very easy to block the NextDNS SNI.

What is harder for people to configure is IP based blocking. Would it be possible for NextDNS to allow us to link our own, custom domains, to a profile to allow us to bypass some forms of common blocking and get our DNS setups to work on more networks?
