Taking full Manuscript and download

So, after doing all the work and taking time to read and re-read, when I am down with all 23 chapters I really wish there was one button for downloading it on to editor. Instead we have to go through all of them and download. If I am missing something please tell me, this is taking forever. Yes, I prob should have did it as I went, but I missed that, so now Ive come here with a suggestion.
