Publish Photobook without using wizard
Is it still possible to make a photobook WITHOUT using the Lulu Studio Photobook.
Unfortunately this wizard publisher tool is hard to customize. Being a designer myself I will rather upload a pdf for both book and cover.
But so far I don't see the option to do that. When I try to edit a photobook it goes directly to the Studio wizard.
Is any option to avoid this and upload a pdf?
