Domain Overrides for the DNS server

Hi.  I am tasked with building a new opnSense router to replace our existing pfSense router.

On the pfSense router we use "Domain Overrides" feature of the DNS server to point to our internal DNS servers for our internal domains.  I'm not seeing a similar option in opnSense.  Am I missing something?  Is there a DNS Server package I need to install for that option?  Your guidance and patience is appreciated as I learn the opnSense ways.  LOL.

Thanks, but "Services > Unbound DNS > Overrides" isn't what I need.  That only allows for individual hosts defined on the opnSense router.

I need the DNS server on opnSense to query specific servers for specific domains rather than starting with the root downward.

For example, we have an internal domain named "example.org".  On the DNS server on pfSense we can create an entry that says for "example.org", ask DNS server "192.168.1.100" for anything about/under "example.org".

Oh.  I found it.  I must be going blind.

Ah ... yes that was changed some releases ago. Before that it was all in Overrides, now forwarding is separate. My bad.
