This function does not exist, but would be nice.

I have created a workaround for seeing the underside of a face down card, and it involves a private notecard updated with a list of a player's tabled cards. The notecard is updated with its description field to list the cards out on the table, and the script sorts the text according to the cards' positions on the table.

At the moment, in the current version of the script, the notecard is updated when a new card is moved into the player's scripting zone, but if they rearrange them, the order on the notecard is not updated. I could get around this with an 'Update' button, or I could use a timer if such a thing existed, but it would be nice if a scriptable event were triggered on moving an object within a zone - specifically on putting it down (no point in processing every minor move through the air).
