Edit multiple cards at once in addressbook
I have many contacts in my addressbook. Now, I want to add a label called 'category' in my addressbook. The category should e.g. be used for work-related cards. I have now three questions:
1) How can I add a label to my addressbook which can be used for all my cards? Currently, when adding a label, I only get it to work for one single card.
2) How can I make a smart list with this new label 'category'? I currently see only standard labels, when using a smart list.
3) Upon adding this label to the addressbook, how can I make sure that multiple cards containing the label 'category' can be filled with 'work' at once? I am only succeeding to fill in the label 'category' once per card.
Thanks!
