I have set up my system so that Org asks for a buffer name every time =org-edit-special= is called. This may be helpful to you.

  -k.
 

*** Custom Python Session Names

https://github.com/jorgenschaefer/elpy/issues/383

I want each python session to optionally have a unique name, so that I
can run multiple sessions in multiple windows/buffers/directories and
not have them interact/interfere.

Here I've copied =elpy-shell-get-or-create-process= from =elpy.el= and
modified it. I also have to modify =python-shell-get-process-name=.
This all is fairly easy, except when executing from Org it gets more
complicated, hence the special case if a function called from
=org-ctrl-c-ctrl-c=.

    "Get or create an inferior Python process for current buffer and return it.
    Customized by KDM to make dedicated sessions"
    (let* ((bufname (format "*%s*" (python-shell-get-process-name t)))
           (proc (get-buffer-process bufname)))
      (if proc
          proc
        (run-python (python-shell-parse-command) t nil) ;; DEDICATED!
        (get-buffer-process bufname))))
