General Sync facebook contact photos but don't add additional contacts?

view story

http://androidforums.com – I am looking to have my Galaxy S3 pull my contact's photos from facebook without actually adding new contacts from facebook. Essentially, let's say I have 10 friends on facebook. Of those, 6 of them are also contacts on my phone (google account). I would like the facebook photo to show up for those 6 contacts, without adding the additional 4 facebook friends to my contact list. Is this possible? (General)
