I need to add a few FQDNs to Blocked Sites List in a handful of firewalls. For now I have manually imported them via text files to each firebox, but surely there is a way to do this via templates correct? I am not seeing it..
These aren't stored as a policy, so they aren't available as a template.
I'd suggest using webblocker if you're adding FQDNs, as quite often the IPs will land in AWS, Azure, Cloudflare, or similar, and you can inadvertently end up blocking other hosts.

So you are suggesting I block the entire category that the website falls into? I'm almost certain that will not be an option, but is there a way to query a domain on demand and see which category Watchguard puts it into? Similar to how you can do a LOOK UP IP for Geolocation via FBSM -> Sub Services?
You can make an exception for a specific FQDN, in the exceptions tab of webblocker.
The proxy is checking the actual get request with the URL in it, vice the blocked sites list which is just converting the FQDN to an IP and adding that as a blanket block.
