using same table for nextID()

Is it possible, would I have to make a patch, have anyone already did it, so PearDB's nextID() uses the same table, and still have a different sequential for an argument? I was thinking that instead of creating a table and append '_seq' to the name, it could create a new column. I am asking this cause recently I've made a clean up at one of my databases to deliver a script to a client and had to delete 32 tables created by nextID(). It went down from 103 to 72....
