Hi Charles,
Frankly you can't... not would you want to.
Options are generally in clothing (which is what I think you are talking about) not the description people are looking for.
However if you are looking to do very specific urls, descriptions, etc then the products should be broken own into individual products anyway... For instance if you are talking about needing a description for "Blue Scarf" and Red Scarf then this would be what you want to have listed as individual products. From a usability perspective you wouldn't want to come to a page and have the image, etc shown for Blue if you chose Red.
