Unity Player Accounts - Simple Feature Request

Unity Player Accounts seems like a great way to provide cross-platform and cross-device persistence for my relatively simple game - already integrated, seems to work great.

Feature request to make it more seamless and clear for users:

Allow devs to upload an image in Unity Cloud that is used as a background image on the Player Accounts login web page for the game. Currently when the web app opens it looks like you are logging into another game with Unity’s robots etc.

(Honestly this seems so crucial/obvious that maybe it’s already an included feature and I am just missing it?)
