Unable to Export Deck Count

I would like the ability to export my Deck Count when I export my inventory.

This is useful when comparing to other lists about cards that are currently available to be used in decks or cards that are already in a deck.

At the moment, the CSV only has the following data fields:

Count   
Tradelist Count   
Name   
Edition   
Card Number   
Condition   
Language   
Foil   
Signed   
Artist Proof   
Altered Art   
Misprint   
Promo   
Textless   
My Price
