Question/Feature request: Conditional forwarding of all local queries 

Is it possible that all local queries are forwarded to the local DHCP server (Fritz Box in my case)?

So that it works like that

    nslookup printer -> via 192.168.178.1
    nslookup printer.fritz.box -> via 192.168.178.1
    nslookup printer.de  -> via Upstream DNS

With Pi-Hole I could query local devices without a local domain name.
