Ability to add more than 3 email addresses for contact

Room for more than 3 email addresses in the contact details, it is not unusual for people these days to have multiple private and work addresses. I have quite a few friends with more than 3, including myself. Can’t really see why there would even be a limit. Without this it means that many of my contacts have multiple entries as different contacts which can make it difficult or time consuming to find emails from them.
