This will resolve the common archive.is domains using Google's DNS service rather than 18.104.22.168 but everything else via 22.214.171.124 as normal.
edit: Nevermind, your configuration worked. I verified after flushing DNS cache that archive.is was at first inaccessible, and now after a pihole reboot it does resolve. Thanks!
I wonder if this is another way to set up the same thing with PiHole's "FTL-DNS"
