I would like enhanced GUI options to allow for custom DNS for a reservation. Point in case I have a Pihole that I have upstream DNS from OPNsense. Every other entity on my network gets DNS from the Pihole though. I was able to manually edit the configuration file for its reservation and set it to OPNsense, but it would be ideal to have in the GUI (even hidden under advanced) so that any changes don’t overwrite that entry.

Would love this added to mirror parity with ISC DHCP (and I have this exact use-case)
