Updating with Yast2 vs Yast1

Yast1 has a capability for going to the SuSE FTP site and selecting modules for update from the ones available there. I can't find anything corresponding to that capability in Yast2. Am I missing something? Another related question: is there a way to change the default FTP site known to Yast1 to be one of the SuSE mirrors instead of SuSE itself? Is that information hiding, perhaps, in some configuration file for Yast? Paul Abrahams
