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}

HTH,

Chuck
