Configure Syslog to log a certain log-level to an alternate file, and then just 
use  "-j LOG --log-level <level>". ie: if you wanted it to log as a notice, 
just setup Syslog to log notices to another file, and drop in a line that reads 

iptables -A LOGGING_TABLE -j LOG --log-level notice --log-prefix="NF: "

I'm not too up on Syslog myself, so you should read the docs for that, but I do 
believe it is possible to log specific log-levels to an alternate file.
