Hi!
In a sort of, you can, i did it once. I played with Federer vs ..., but when you win a game, umpire said "game Federer"...also if i made break, umpire said "game...", even when you put "ann_game1" or "ann_game2".
You needed then to play with players that umpire said name

, and change everytime you change players.
There is no file to do this "individual", i mean for each players.
Hope i was clear
