I recommend looking into org-edna
(http://www.nongnu.org/org-edna-el/#conditional_forms).
You can try to use "has-property" in combination with "set-property" as
a TRIGGER.

Alternatively, you can customize org-property-changed-functions (see
https://www.reddit.com/r/emacs/comments/7gr9ps/add_logbook_entry_and_note_on_orgmode_property/)
and reimplement org-edna functionality for your purposes.
