Very simple question; renaming (not changing!) a class

I was about to post a request concerning mage kits, but after thinking it over I think this would be the wiser/easier option.

Depending on the AD&D edition, when you specialize as a mage, you are able to choose which spell school to give up. Since that's not entirely the case in baldur's gate, I was wondering if it was possible to choose the spell school I'd like to give up, and then rename the specialized school (I saw in ee-keeper you could only change kits, not rename them.

As an example:
1. want to be an enchanter at the cost of illusion
2. pick necromancer
3. rename class enchanter.

Any ideas?
