You probably want to use the Batch functionality in the PageTemplates
library. It's dead easy. Probably docs on zope.org and examples on
zopelabs.com (and in source all over the place.)
"Code generators follow the 80/20 rule. They solve most of the problems, but not all of the problems. There are always features and edge cases that will need hand-coding. Even if code generation could build 100 percent of the application, there will still be an endless supply of boring meetings about feature design."
