Issue / Feature Request - Remember boot device order

It would be very useful if I could set removable boot devices to be higher in the boot priority whenever they are plugged in. I have automated restore disks for my system and the only thing keeping it from it working without me needing keyboard or monitor is that whenever I unplug my flash drive or dvd drive and reboot, when they are plugged back in they are moved back to the bottom of the boot list, so I need to go into bios to move them back up. I've seen other computers where the bios has a place holder for DVD or USB flash drives so they can be placed higher in the boot order, even if they aren't currently plugged in.
