I have a 12 x 9 8 pg book and the bindery person wants to run the cover head to head but everytime i rotate the spine is on the outside and I cant get the file head to head with the spine in the middle
Just do the cover as a Montage
or
build yourself a custom Scheme
that does what you want.
Custom Scheme would be the best
as you could have it in the future
as a "Scheme" or "Product Part".
