iphoto How to bulk modify the image to take the address?

Feel a piece of change address information too troublesome, so many photos, is almost impossible task, seemingly iphoto can only batch modify the name date and so on, what method can bulk modify the photo address information Ah!

If you are accustomed to managing your photos by incident, such as the Hong Kong Disneyland event theme, select the event directly, click "I" (or press Cmd+i), and then enter "desired address" = All pictures in the event will be accompanied by the "required address", and later drag and drop the merged picture (no additional address will automatically add the "required address" and the original address will be retained if the address is already attached.
