Feel free to generate your own set of tables for any SSID you like.
As for adding it to the original set, it's our contribution and no sense in changing it. You can distribute it yourself, it's easy enough. Current stats show us having pushed 922 Terabytes through the Shmoo's tracker. I don't want to ask them to do more than they offered.
The coWPAtty README has instructions on how to generate you own table, about 2/3 of the way down the file. Just search for "genpmk" and you should see it right away.
