When will the new items be added to gameflip ?

Is there any chance that uncommon wheels and the new Nitro Crate items to the list of items you can sell in Rocket League ?
Also some people are able to upload custom photos, which I don’t know how they do, does anybody have an idea?

Hey! We are working hard to add these item as soon as we can.

We will keep you posted.

Thank you for the suggestion!
