Fusion Drive: How do I manage which software is on the Flash portion?

Any idea how I can see which software Mountain Lion is placing on the Solid State portion of my Fusion drive? Can I manaually manage it, as they suggested?

From the link below, it is suggested that once I add a partition to my Fusion drive, the "plus" symbol in Disk Utility to add additional partitions will be grayed out. You cannot partition the Flash storage. When I go to my (Apple configured) drive in Disk Utility, there is NO plus sign next to my drive. I haven't attempted any partitions. Is it possible that my drive was not formatted properly from the factory?
