Sync whatsapp contact photo to iPhone contact photo

people usually have a photo on their WhatsApp profile. i would like to use those photo's in my contacts. Is there a way to sync the WhatsApp contact photo's to the iPhone contacts. (please don't tell me to save the contact photo for each contact to the camera roll and connect it manually to the appropriate contact in the iPhone Contacts app, I know that but I'm looking for something smarter and more automatically than doing it one by one manually…)
