Does the attached file here work for you? I use it and it seems to do what you
describe.
https://lists.gnu.org/archive/html/emacs-orgmode/2014-08/msg00109.html
My full archive setup from my emacs.org follows. It is based on the above code
but tweaked in ways by past-me that present-me doesn't fully understand, but it
works for me.
