I can't help you with customisation but I am curious - can we see squid.deny-useragenst contents? :-). Where you get those?
I got them from: http://www.bleedingsnort.com/article.php?story=20050303190103553
But this list does not work for squid of course so I converted the file a bit and selected only the Malware and P2P stuff.
Since I am new to this list, I do not want to post the txt file here, because it might be a little bit too long (10 kb), about 75 user-agents.
If somebody wants it, please send me a mail or tell me if I can post it here.
Regards, Alexander PS: Hope the reply works...
