There should be a way to allow Anaconda to log all the system information to a disk pre-install. You take that disk to another system, go through all the menus based on the logged hardware information, and then bring it back to the former system with all your choices and it runs through an unattended install. This would help in two cases: A) Your computer is in a place you don't want to sit around in (i.e. its a firwall in a cold basement B) Your computer is so darned slow its aggravating, or doesn't have a mouse. C) Insert your reason here. Maybe an extension to kickstart?
We do store most the settings into the anaconda-ks.cfg file after you complete an install. We don't have plans to use this data for scripted install sections. If you want you can take the anaconda-ks.cfg and tweak it by hand, and then insert 'interactive' in it as well and you will have something close to what you are describing.
