You don't. Only the listed fields can be import targets for that dialog. The alternative is to write your own import code or use a third-party tool.

I am importing a list of contacts from Excel into Outlook 2003. I want to
import to the "Nickname" field, but when I get to the "Map Custom Fields"
window, it isn't listed. How do you add fields to be available in "Map Custom
Fields"?
