UTM 9 - Allow Site based on Keyword (not URL)



Is there a way I can allow sites based on keyword in UTM9? This is for web content, not URL (if possible). I'm dealing with 'uncatergorised' site issues so figured if I could allow them based on a keyword that would be great and would stop me from using uncategorised: allow. The URLs change, so this is why the URL method is not really good for this situation. For reference, these are agency sites, so anything that would contain the word contractor or agency would be allowed, but obviously the URL could be djcivil.co.uk (contains none of those words..) 


Any help appreciated,
