combobox and listbox question

I have a user table in my database with an alphnumeric primary key field
called userid
my record looks basically like
userid = "es", name = "eli silverman"

use additem to add the names to a combo/listbox but still be able to
reference the primary key when selecting the value.

I know how to use itemdata to associate a numeric reference value with my
list item. Is their any counterpart, similar to tag, that can associate a
unique text value with each of the list items?

Any help would be greatly appreciated.
