saving certain words for T9 Word

i had the voyager and i always used the "Word" option on the fron screen. And when i would type a word and it didnt have it as an option, i would go through and typr each individual letter in the "abc" format. And when i would use that word again in the "Word" format, it would remember it. Does the chocolate touch hasn't been doing it the same way. Is there somehoe i can save words so it will recognize it in the "T9 Word" format?

  THANK YOU THANK YOU THANK YOU!!
