if auction is created like a post, why can not see it like a post?

Hello there,

When a new auction is created, I guess it is made like a post. I supose that because when a single auction is shown, it seems to use single.php WP core file.

Is that right? If it is Yes, why cannot see auctions in WP BO like the other posts?

Thanks.
