When creating a dropdown list, how can I have an item appear for choice but
output from choice an abbreviation? Example, I have a department list in
namedrange DEPT.
ACTG (Accounting)
PURC (Purchasing)
INVT (Inventory)

I want the user to see Accounting, Purchasing, Inventory, but the output
from their choice to be the appreviated version (ACTG, PURC, INVT).
I don't want to display the entire thing to the user only the description.
Any way to do this?
