change name of save profile

Hi,I'm wondering if anyone knows how to change the name of a profile you've created in a game without having to play the game over again.... same idea as the "save as" in word or something.
I used a profanity as my profile name because I was pissed off at the game since it kept losing my save data.
Now, my 10yr old cousin is getting into video games and constantly plays with my DS. I don't think kids should be exposed to profanity so I want to change it before he inadvertantly sees it.Is there a way to do that without re-playing the entire game over?The profile in question is in "Brain Academy" if that helps.thanks!

There is no in-game solution; there might, however, be a more technical solution that I am not aware of.
