In answer to your question: Nope. There isn't one in the books/movies/supplemental material to date.
Would it be nice? That can be subjective. Spells can backfire, and a person could be doomed to read/absorb too much information in too little time and overload their brain. Much like Lockhart who attempted to do something 'nice' (subjectively) in modifying Harry and Ron's memories, and instead ended up erasing his own.
AFAIK, magic can be used to enhance or alter what is already a part of a person--for example, the Snorus spell that Bagman/others use in Goblet of Fire to project their voices, or magics involving human Transfiguration like Polyjuice. It is used to grow/shrink, make a person sleepy, make a person fly, grow their bones back, etc. Magic can be used to take things away; again, Lockhart, or when Voldemort quite literally ripped up his soul. However, to my knowledge, we never see examples of magic increasing a 'person' in a permanent manner. We never see additions, however. If a wizard/witch wants to improve themselves, they have to do it the same way as Muggles--with lots of practice and studying.
