Comment 7 for bug 34523

By the way, I sort of agree that this would be nice, but it is extremely difficult due to the ordering of events in the installer; network access isn't available yet at the time those questions are asked, and they need to be asked early in order to provide properly translatable network prompts and a properly configured keyboard so that you can respond to them. That's why this bug has been stalled as wishlist for some time; that doesn't mean that bug triagers should feel free to come along and close it.

It might be easier to do this in ubiquity (the live CD installer).
