That will be added, hopefully before retail but if not then soon after. With that update, isostick will be able to show up as more than just an optical drive and a flash drive -- it could show up as another hard disk / flash drive as well, using a disk image. I'm also looking into supporting up to 6 virtual drives at once (optical or hdd), but no promises! The CPU in isostick is a beefy one but RAM is still limited, if it's possible though you can bet it'll show up in an update!!
I would be very interested in seeing isostick supporting .vhd files for direct access as hard disk drives.
