For me (99% of my games are with a machine empire) it would be the amazingest thing if I could capture a "snapshot" of an existing planet's districts/buildings, and make the automation build the exact same thing on a new planet when I set it to a designation. If I could set up the sequence and pop count triggers for when certaing buildings/districts get built, that would be golden.
So basically, if a planet is a generator world, build these districts and these buildings in X order. If it is a forge, build different districts and buildings in Y order, and so on.
