I guess what you are asking makes sense, but I think that it would be a little bit complicated to do. Perhaps a re-learn feature, where you play the tracks, and VE checks which notes are changed, if any, and then loads the appropriate samples.
However, this features would only be quicker if there was a global learn and re-learn button, as in most cases it would probably be quicker to load the whole instruments than to play the track!
