batch update display name in AD ? possible ? 1

[fatchai]

hi :

i have hundred of users that require to add location name (same name) in their display name

for example: current their display name are
Pan, Peter
Smith, Mary

I need to update them into
Pan, Peter (Atlanta)
Smith, Mary (Atlanta)

IS there any faster method that i can update them in batch instead of one by one using rename

cheers
