It looks like I can generate independent signals for clocks and some other signals, but not for the address signals. I know how configure the wizard for two chips that share the same address lines.

When reading page 1-4, it seems to say that the controller can handle chips that are located on opposite sides of the device, but it does not indicate whether the chips can be completely independent (signal-wise) of each other.

You still think it should be possible?
