How to display game image on Oculus dashboard, from an "Unknown Source" app (running via Steam)?

Hello, where do you specify the image to use when you are in-game and press the Oculus Dashboard button? Currently, I see the image of the broken image/mountains look instead of my Hero, Cover, Logo, Icon, any of the assets on the Oculus site. 

Okay, figured out that this only occurs if the game is launched via the Steam product instead of the Oculus store version. When you launch via Steam, Oculus treats it as an "Unknown Source", so it doesn't have the information to display the image. 

My follow-up question now is, can we include an image in our Steam version, that the Oculus Dash would read from? So the image isn't the broken/missing version, and would instead show the correct image?
