The Palm OS in my old Palm V had an option when you edited the details of a Phonebook Contact... "Show in Lists." It would allow you to choose which of a contact's phone number (home, mobile or fax) will appear when the name was in a list or when you used the "/ L" Lookup shortcut.

This appears to be missing in the PhoneBook of my Treo 180.

Anyone know how to make that happen or why they phased this neat option out?
