It's a private function and I need only a part of it.
Should I extract that part and create a new function? Like this below?
(defun first-line-docstring (fun)
(let* ((doc (condition-case nil (documentation fun) (error nil)))
(doc (and doc (substring doc 0 (string-search "\n" doc)))))
(if doc
(format " -- %s" doc)
"")))
Or just copy the needed part and put it in org-columns-new?

OK. Based on this example
https://emacs.stackexchange.com/questions/74547/completing-read-search-also-in-annotations
I came up with this snippet below:
(completing-read
"Summary: "
(lambda (s pred flag)
(pcase flag
('t (all-completions s
(mapcar #'car org-columns-summary-types-default)
pred))
('metadata (list 'metadata
(cons 'annotation-function
(lambda (c)
(first-line-docstring
(cdr (assoc c
org-columns-summary-types-default))))))))))
Thank you for the feedback.
