Add as a new contact

I would like to have a feature to add a changed contact as a new contact. Currently, the two options in the edit screen for a contact are save and delete. I'd like to see another option added as save as new contact. This would be useful when adding another contact that is from the same company or family, in which many of the fields are the same. Like this, the user would be able to change only the fields that are different in the new contact from the existing and save the changes as a new contact, saving the trouble of entering all the duplicate data. This feature would be similar to a copy the contact feature.
