Where can I setup the promotional image for my in app purchase item on iOS11?

"Promote your in-app purchases

In iOS 11, subscriptions and in-app purchases are shown in separate sections on your product page, and you can showcase up to 20 total items. Each item you feature can have a unique display name, promotional image, and description." quoted from https://developer.apple.com/app-store/search/


I can't find the place to setup the promotional images for my iap items.

Any one found how to setup?

Its gunna come soon, thats what it said on iTunes Connect on the home page in the news section. im pretty excited about it, probably gunna be a cool new feature.

It seems to be there now, however, it's broken. As soon as I drop a JPEG image in there it suddenly gives me warnings saying my In-App Purchase Descriptions are too long. It causes them to become limited to 45 characters which is obviously a bug, so I filed a bug report with Apple.
