Item Customization Packs - Display Contents

The new item customization is a great feature, and I'm really enjoying being able to pick how my gear looks.

The option to buy customization packs at the Watch is great, but I'd really like to collect as many of the materials as possible the old-fashioned way. However, I have no way to identify which ones I am missing.

I would like to suggest that the purchasable packs display the appearances they contain, and tick off the ones that the player has already collected. Alteratively, this could be a page in the codex?
