Yes. Quite a few.
If you want is the src block name to be used as the caption,
you can put this line:
#+CAPTION: use-name-as-caption
before the named src block
and execute this code before you export:
#+BEGIN_SRC emacs-lisp
(defun org-export-use-name-as-caption
(text &optional back-end info)
"Use the block name as the caption."
(replace-regexp-in-string
"label{\\([^}]*\\)}\\(use-name-as-caption\\)"
"label{\\1}\\1"
text))
(add-to-list 'org-export-filter-src-block-functions
'org-export-use-name-as-caption)
#+END_SRC
Then when you export this
#+CAPTION: use-name-as-caption
#+NAME: y-plus-z-becomes-x
#+BEGIN_SRC R
x <- y+z
#+END_SRC
the result is
\begin{figure}[H]
\begin{verbatim}
x <- y+z
\end{verbatim}\caption{\label{y-plus-z-becomes-x}y-plus-z-becomes-x}
\end{figure}
