Drop Cards onto Character Sheet?

Is it possible to give attributes to a card so that it can be dropped onto a character sheet?  Basically, I want to have cards that represent items and loot.  When a character earns treasure, they draw a card.  They can then drop this card onto their character sheet to add it to their inventory (like a compendium item).  Is this possible with character sheets or the API?

You cannot drop it onto a sheet, but if you deal a card to a player (drag it onto their name in the player list on the lower left), it is persistent between sessions. I use this method to track consumables like potions. You can also distribute items as handouts. When you give them to a player, change the permissions on it so that it is visible to the player who owns it. You can also create folders in your journal tab for each player and move the handout to the person who owns it. Many thanks to The Aaron, for both of these tricks.
