Name associated with a phone number or email are no longer customizable in address book.

In the past, when I would create a contact, i had the option to customize the label associated with a particular number. For example - for my entry for Joe & Mary Smith, I could put each of their numbers in and specify whose number was whose. I would just hit customize, and type in either "Joe" or "Mary". Since the last iOS update, that function is gone. Now I just get a long drop down list but custom is no longer listed.

I do in-home sales, and my customers can include multiple people in one house. Not being able to list which number is whose, is a huge loss of functionality for me personally. The work around is I put the phone numbers in the Notes section. But then I'm not able to tell Siri to call an individual. I have to go to the contact, scroll down to notes, engage Siri and verbally give her the number. Big loss of convenience!
