Merging contact information

I have a Google, Facebook and LinkedIn account and all are connected in my Android contact manager. What I am looking for is a way to move all the information from the Facebook and LinkedIn accounts that I did not already have with Google. For example, when I connect a FB contact in my phone it has birthday, email, phone and other bits of information that I did not have saved in my Google contacts.

Ideally I would like to find something that syncs the other information back to Google automatically and not just a backup app that gives me a CSV file. Does anyone know of any good solutions for this?
