We suggest a new Option Document in the field "Salutation Type" in Table Salutation Formula (5069) used in Sales and Purchase Documents in the of using a Person contact in the address field. This is very helpful especially if the contact "First Name" is unkonwn.

Example:
Creating a new personal contact with only the last Name (for example Schmidt) connected to a company contact (for example Add-ON Marketing).
Creating a new sales quote for Add-ON Marketing, insert that new contact Schmidt in "Contact No.".
Print the sales quote. The printed Adress in the sales Quote is:
Add-ON Marketing
Schmidt
435 Kingston Street
New York, NY 11010
USA

and that is not very polite.
It whould be helpful if there is a salutation code for document address, which whould be "Mr." in that case:
Add-ON Marketing
Mr. Schmidt
435 Kingston Street
