Please add the option to batch add a page to a set of files. Multiple options and uses, examples: 1) Add the same cover page to a large set of pdf files - append or addend the same pdf to the front/end of a selected set of files. 2) Add a section cover page to a set of pdf files - collate the first page of a pdf with the first file, second page of a pdf with the second file, and so on. 3) For two sets of files (the same number of files in each set), append or added the first pdf of the first set to the first pdf of the second set, and so on to collate them.
Include an option to bind all the files into a new pdf, save as a new set with filename appended, or save over the original files.
This will allow a fast way to add cover pages to sets of documents.
