How to apply flat rate to a specific zip code?

I am using the ups plugin from alatak and it works great. I need to be able to set a handful of local zip codes to a flat rate price. Is this possible and where would this edit be done at?
Thank you for any help in this matter.

well, the std. weight plugin will do this (if non Can, NL and UK numeric) but u have to exclude or put up with UPS also offering a rate
or hack the UPS to ignore the required postcodes.. see the checkConditions() function in the UPS
