It effectively does have this capability. Just disable all the standard filter lists, and manually add one's own entries to the "my filters" section.

This method has the added benefit of enabling other useful privacy features that don't directly relate to display advertising, like killing off the nastiness of hyperlink auditing, CSP reports going to 3rd parties, prefetching, and remote fonts.

Is this per the ad network / server, or per domain like the whitelist? I would have assumed the former, but if it works like the whitelist that's great!
