family only mode

Hi I would like to see motion alerts only go off when it's a random person at the door and not family members, then if it did go off then at least you would know it was someone other than family members. You could have a setting called family only mode similar to people only mode, so once a family member walks up to the door you press a capture button and put the face into a profile of some sort and then when that person walks back to the door another day it remembers the face and the motion won't go off.
