Deck File Format: A Request

The current deck files requirement to specify a Card Number and Set in order to display a specific image file for a card is overly complicated and very time consuming. The exact same effect could be achieved for 99% of all MTG cards by simply specifying only the Set that the card comes from. I have seen similar requests while searching about this topic on the internet. Is there a reason why this functionality was never implemented or are there any plans to add it in the future?
