Ability to set secondary and tertiary DNS servers in PH DHCP

[jfb]

To clarify, your feature request is to have the option to offer a second DNS server when Pi-Hole is the DHCP, and you want it in the web interface?

Is this the feature you want?

DHCP-Option-6 integration in the GUI

We intentionally do not offer a one-click solution for adding a second Pi-hole through the DHCP settings as we have no way of synchronizing statistics between multiple running DNS servers. Such a feature is on our long-term to-do list, however, it has somewhat low priority at the moment.
