Could you support setTemplate page by page form the external document?

I have a external PDF document , it has 10 pages. I want to create a new PDF, which also has 10 pages. And every page is the same as external PDF when page number is the same . I just want to add some watermark string on the top of the page. But now,it seems can`t achieve

You are right, this cannot be achieved with pdfjs right now. While there might be a workaround by adding each page as a background image, I wouldn't recommend going that route.
