Is there a way to have my "system" drives become double drive letters?

With the addition of card readers in my user's machines, my Windoze boxes
default the card readers to F: and such. I change those manually but
sometimes they change back. Instead of making Windoze change I figured
I'd see if Novell has a clean "elegant" solution. I know you can do
search drives for first availible but I like being able to depend on F: as
sys or hopefuly AA: to be Sys

Is there a way to turn F: and Z: into AA: and BB:?

Just curious. Yes I know there's a whole alphabet there and I do need to
consolidate volumes and sub-drives to clean up my network, so this is more
a thought exercise and seeing if I could do it for my login, not my users.

Thanks in advance!
