        Actually you can accomplish this by using additive (but you would have to
make sure all "bad" communities are caught and the values reset to a valid 'standard'
route prior).  This would allow you to know anything past this point is a valid, 
acceptable community which would leave you with checking  null0, then local pref's 
and setting it properly..  


I can supply a config, if folks are interested.
