Infix Address Book

In the Netherlands (and i suppose in other countries) we use a "tussenvoegsel" which i believe is called a "infix" in english. It's a surname (last name) prefix. I can't find this field in address book and the result is contacts being sorted by the most common infixes "de" and "van". So basically, 90% of my contacts are sorted under one letter.

The simple workarounds are to use the middle name field, put the infix behind the last name or behind the first name, but that's a fast and dirty way of getting it to work.

So, am i overlooking something? Does anybody know if this is possible in address book (and if infix is the correct name for this) ?
