Upgrading Madden from Standard to Deluxe

I recently saw that Madden is doing instead of 3 day early access, they are doing 7 days and I wanted to upgrade my standard edition purchase to the deluxe. When I look on the EA app on PC though and add the deluxe edition to my cart, it has the game edition going for full price. How am I able to upgrade my Standard edition to the Deluxe to get the 7 days early access?
