Is it possible to add new banners in Arenas?

Hello,

I'd like to know if there's some way to edit arenas, in order to add new banners for new teams titles or new reserved players numbers?
In the arenas i've could download from Chicago Bulls, there's not Scottie Pippen No. 33 hanging on ceilings... Is there any version of the Bulls arena that includes it?

Thanks to everyone here for the remarkable work you've done customizing and updating the game.

Regards

Yes you can edit the arenas.
There is a tutorial and download section to help you with this.
