Embedding Text

I heard people say Embed text and I was wondering if you could kind of break text into an object, or embed it. I was wondering if I could do this because I have a movie clip where the text on the button (or movieclip) simple travels down on the RollOver. Well I want to make it so I could just copy buttons and just embed differnt text into the different copies so when the botton travels down, even though they are copies, they all work with different text. Does anyone know how to do this? Thanks.
