Setting contact picture from linked contact

I use Local Sync as my main address book. Several of my contacts are linked to different address books (e.g. LinkedIn, Skype, Whatsapp, Viber). In my case, I found a contact having a very beautiful photo in Viber but I chose to set an old ugly picture in my address book The question is: how do I tell Android to select the contact picture to display for a given contact not from Gallery/Camera apps but from that same contact's linked Viber account? The question can be generalized and rephrased to cover not only Viber:

how do I tell Android to select the contact picture to display for a given contact not from Gallery/Camera apps but from one of that same contact's linked accounts?
