Option to download html and pdfs

Perhaps I'm being unnecessarily evidence focussed, but I try to download all the "originals" when dealing with HMRC. I manually downloaded all the pdf and html calculations generated by your awesome website for reference. A "Download All" option to grab a zip of everything would be super.

Thank you for this awesome little tool. Really really nice job! I'm a software engineer and I appreciate a carefully user-driven design more than most :)
