Block TLDs with Squidguard

[poohbah10]

I want to block top level domains that are known to have a less than savory reputation.  Unfortunately, the Squidguard GUI doesn't like the domains in single element format e.g. "xyz" or ".xyz".

Is there a simple way to create a target category that uses TLDs?

Thanks

I have blocked these domains with Squid ACLs, but a category block would provide better logging if it can be accomplished.

Using Squid ACLs turns out to not be a good choice as entire pages appear to be blocked when only some content loads from the undesirable domains.  Any suggestions to get it working in Squidguard?
