How to wrap Org code generated by a source block?

Hi everyone,

I want to generate some parts of my document programmatically from an
emacs-lisp src block - i.e. the code produces Org markup which I want to
then export. Is there a way to wrap the #+RESULTS block in an environment
that still gets evaluated as Org text (e.g. when exporting)?

More details:

Here's a sample src block which shows the kind of thing I need to do:

#+begin_src emacs-lisp :results value raw :exports results
(mapconcat
 (lambda (b) (format "#+begin_%s
Generated %s block at %s
,#+end_%s" b b (current-time-string) b))
 '("example" "quote") "\n")
#+end_src

Using =:results value raw= in the header produces the result from the block
without wrapping it in any blocks, which is exactly what I need. E.g.:

#+RESULTS:
#+begin_example
Generated example block at Tue Nov 10 15:07:45 2020
#+end_example
#+begin_quote
Generated quote block at Tue Nov 10 15:07:45 2020
#+end_quote

HOWEVER, this has the problem that when I re-evaluate the code block, only
the first block below #+RESULTS gets replaced, pushing the others downward,
so I end up with something like this after a couple of times:

#+RESULTS:
#+begin_example
Generated example block at Tue Nov 10 15:08:42 2020
#+end_example
#+begin_quote
Generated quote block at Tue Nov 10 15:08:42 2020
#+end_quote
#+begin_quote
Generated quote block at Tue Nov 10 15:08:39 2020
#+end_quote
#+begin_quote
Generated quote block at Tue Nov 10 15:07:45 2020
#+end_quote

If I remove the "raw" then the results get wrapped in an example block (or
any other that I specify with =:wrap=), which means they get correctly
replaced every time, but not evaluated as Org text:

#+RESULTS:
: #+begin_example
: Generated example block at Tue Nov 10 15:09:46 2020
: #+end_example
: #+begin_quote
: Generated quote block at Tue Nov 10 15:09:46 2020
: #+end_quote

So again, my question is: is there a way to wrap the #+RESULTS block in an
environment that still gets evaluated as Org text (e.g. when exporting), so
that I can rerun the code block without having to manually trim the results
block afterwards?

Thanks!
