Is full-wrap possible for hardcover with Booksmart ?

Hello,

I’m beginning  to create my book (12" x 12"); hardcover, no dust jacket.

I would like to know if it is possible to place an image on the cover that would go from back to front (or front to back, doesn’t matter at this point), as one single image (consider that it would be one continuous image from back to cover via the spine.

Or must I divide the image in 3 parts and place them on theback/spine/cover asI would do with a double spread inside ?

In other words, am I answering my own question :) or is there a possibility I haven’t seen ?

Thank you for any help.
