I would like to know how to use a pre-set salutation, (assigned to each
contact previously), in a mass mail merge for a client database, where one
letter is being used for many different contacts.  For example, in a templete
saved letter, the preset salutation for one contact is Mr. & Mrs. Smith.  In
the next contact I might refer to the contact as Joe and Mary.

This becomes problematic when I have to manually type or choose a salutation
Word offers me at the time of letter creation.  If I were to have a custom
field field called Salutation, I could pre-fill my salutation of choice in
the contacts area and then just run the mail merge with automatic salutations
filling the chosen letter, specific to each contact.
