Configure to use default forwarder

[centja1]

Is there a way to configure the DNS zones similar to the Conditional Forwarding Zones in Technitium?

I would like to configure a dns zone for example.com to use an arbitrary combination of handlers and then, should there be no answer returned from these handlers, have the query sent to a default handler.

From a fresh install:

1. dig example.com @<<gravity ip address>>:53 - returns the correct IP address for example.com
2. Create example.com zone with only memory and etcd forwarders
3. dig example.com @<<gravity ip address>>:53 - returns NXDOMAIN
4. Add forward_ip handler to 1.1.1.1:53 to example.com zone - returns the correct IP address for example.com

I think, essentially, I would prefer to not have to add a forwarder to every zone and just configure my default forwarder once while still retaining the ability to forward specific zones to different DNS services.

Is this possible?
