"insert the same pdf file" with batch processing

[yonghuiz46691490]

many PDF files with single A5 page, but I need to print two copies in one A4 page. I have tried a lot of way, but failed. the only way is to insert (copy)  itself firstly, then print multipage. so I would like to setup a batch processing with insert itself and print. but I don't know how to setup "insert itself". Any recommendation? ! thanks!
