Also arrange your publisher set so all the PDFs are in one folder.
Select that folder and tick the "Merge to one PDF file" box.
Whatever the name of the folder is, that will be the name of your PDF file.
If you have multiple folder inside another folder as in this image, you can merge the parent folder or the sub folders.
