menu selection in config.sys

I have a dos bootup disk that uses a menu in the config.sys file which
allows a selection of which nic is installed in a machine. This is to
alllow whichever machine we have to connect to the server, for ghosting. Unfortunely the menu only allows 1-9, and we now have more nics to select from, and I’m sure the list will continue. Can anyone tell me if there is a command that allows for additional menus or can expand this list that works in config.sys?
