Change AD Imports and User names

Change AD Imports and User names

Is there any way to change the "User Name" in PMP to use anything other than First Name Lastname from AD?  (without changing the AD data, which is correct)
 
The reason is that we have a number of users that have the same first name and last name but different initials.  PMS imports all of them as the same. 
 
Example:
 
Fred A Bloggs and Fred B Bloggs are in the AD as
 
First name: Fred
Initials : A
Last name : Bloggs
Display Name: Bloggs, Fred A
 
First name: Fred
Initials : B
Last name : Bloggs
Display Name: Bloggs, Fred B
 
When imported the both appear as Fred Bloggs.  
 
Could the program be modified to use the Display Name?
