One single .odt document.
Some pages are portrait, others landscape orientation.
At the moment two page ranges: 1st with portrait, 2nd in landscape.
Pages need to be reordered, means pages, landscape one to move to document front.
In future, when document gets more logical parts, maybe further reordering will be needed.
