Very nice thanks however one question.

I started as test with 


#+begin_src 
** TODO Test
   :PROPERTIES:
   :Sent:     [ ]
   :END:

** WAIT Test2
   :PROPERTIES:
   :Sent:     [ ]
   :END:

** TODO Test3
   :PROPERTIES:
   :Sent:     [ ]
   :END:

#+end_src

I then used the code:
#+begin_src elisp :noexport
(defun test/set-property-at-heading ()
  "Function to be called at the beginning of an Org heading."
(interactive)
  (let ((el (org-element-at-point)))
    (org-set-property "foo" (org-element-property :title el))))
(org-map-entries #'test/set-property-at-heading)

#+end_src

And indeed ended up with 

#+begin_src 
#+COLUMNS: %TODO %40ITEM(Task) %40SUMMARY(Summary) %Received(Rec)
** TODO Test
   :PROPERTIES:
   :Sent:     [ ]
   :foo:      Test
   :END:

** WAIT Test2
   :PROPERTIES:
   :Sent:     [ ]
   :foo:      Test2
   :END:

** TODO Test3
   :PROPERTIES:
   :Sent:     [ ]
   :foo:      Test3
   :END:
#+end_src


However I wanted to insert a checkbox not a title so I tried 

#+begin_src 

#+begin_src elisp :noexport
(defun my-set-property-at-heading ()
  "Function to be called at the beginning of an Org heading."
  (interactive)
  (let ((el (org-element-at-point)))
    (org-set-property "New" (org-element-property "[ ]" el)))))
(org-map-entries #'my-set-property-at-heading)
            
#+end_src

But this did not work, I am either asked all the time (but I have 200
headers), or it does not work at all. I also tried

#+begin_src elisp :noexport
(defun my-set-property-at-heading ()
  "Function to be called at the beginning of an Org heading."
  (interactive)
  (let ((el (org-element-at-point)))
    (org-set-property "New2" (org-element-property :checkbox el))))
(org-map-entries #'my-set-property-at-heading)
            
#+end_src


Thanks again
