Tables :: Merge Duplicate / Similar Records Into 1 Record In Access 2010

Is there a way to merge duplicate/similar Access 2010 records into one record?

I have an Access table with 1,000 duplicate records, although they are similar and not exact duplicates. As you can see below, some records contain information that other records do not. Yet, the primary key is the same for all duplicate records. I want to find a way to merge data from filled cells of duplicate records into empty cells for each duplicate record. I do not want to concatenate the data (i.e. combine last and first name, etc.). I only want to fill empty cells if there is a match for it in a duplicate record. I will delete the newly exact duplicate records later. Short of correcting the records by hand.

Example

Code:
LastName FirstName SSN Address Phone Email
Doe John 123-45-7891 123 Anywhere St. NULL john(at)gmail.com
Doe John 123-45-7891 NULL (123)456-7890 NULL

Desired Result

Code:
LastName FirstName SSN Address Phone Email
Doe John 123-45-7891 123 Anywhere St. (123)456-7890 john(at)gmail.com
Doe John 123-45-7891 123 Anywhere St. (123)456-7890 john(at)gmail.com
