Yi Jianlian's first name on his jersey?

I created and added Yi Jianlian to New Jersey Nets roster. I put Yi in FNAME line, and Jianlian in NAME line. I just saw some NJ Nets game, and he has his name Yi on the back of his jersey (just like Yao Ming. Yao is his name, but Yao is on the back of his jersey). I don't want to change FNAME to NAME ( I don't want to put Yi in NAME line) because in game stats, He would be presented as Jianlian Yi.
So which value I have to change to get Yi on his jersey, without renaming his FNAME to NAME

I'm yet to discover how to do that without reversing the names but until then, that's the only way of doing it.
