Sorry, I was using that long time without observing.

There is main name and sub-name.

Here now you can customize it:

;;;; ↝ RCD TEMPORARY BUFFERS

(defvar rcd-temp-buffer-mode-history nil)

;; You may customize the main name here:
(defvar rcd-temp-buffer-name "RCD TEMPORARY BUFFER")

;; You may customize the modes you wish to get asked with prefix C-u:
(defvar rcd-temp-buffer-modes '("adoc-mode" "emacs-lisp-mode" "lisp-mode" "markdown-mode"
				"org-mode" "sql-mode" "fundamental-mode" "html-mode"))

(defun rcd-temp-buffer (&optional name mode)
  (interactive "p")
  (let* ((format (concat "*" rcd-temp-buffer-name "%s%s*"))
	 (buffer (if name (format format ": " name) (format format "" ""))))
    (switch-to-buffer (generate-new-buffer buffer))
    (if current-prefix-arg
	(let* ((mode (completing-read
		      "Mode: "
		      rcd-temp-buffer-modes nil t nil 'rcd-temp-buffer-mode-history)))
	  (funcall (intern mode)))
      (funcall (intern (or mode "fundamental-mode"))))))

(defun rcd-temp-buffer-destroy-em ()
  (interactive)
  (kill-matching-buffers "RCD TEMPORARY BUFFER"))
