I have a file setup with several alternate layouts. One is a print document and the rest are various digital elements (email, landing page, etc.). I'd like to export all of the digital ones at once to make a compiled pdf. Is there any way to do this? I've tried adding all the names to the export box, but it never works. Having to save individual PDFs and then merge them is a huge pain. They need to remain as individual alternate layouts, FYI, so combining them is not an option. Help!
