Pretty simple. I expected to be able to right click from a city to set a point for units built to emerge, or for units ungarrisoned to appear, but that doesn't appear to be the case.
This is pretty annoying if you have units popping out onto rough terrain with a road on the other side of the city, and has gameplay implications beyond a few wasted turns if you have a hostile enemy army en route to another city nearby that needs reinforcements.
