Hi Ihor:
Do you have a patch? I’m not an org-mode user so I can’t test this myself.
Thanks

________________________________
Hi,
I'd like to request a new ESS feature that will allow to choose which
session is created by ESS when no session is yet associated with a
buffer.
Currently, `ess-request-a-process' unconditionally re-uses an existing
ESS process with appropriate `ess-dialect', even when such process is
not consistent with `ess-gen-proc-buffer-name-function'.
This behavior puts Org mode's ESS support in somewhat difficult position
- Org mode allows multiple sessions in Org src blocks, and we want some
way to tell ESS which session process to use for any given buffer
without actually starting that process manually.
We had a hope that setting `ess-gen-proc-buffer-name-function' would
suffice and that ESS would start a new process according to
`ess-gen-proc-buffer-name-function' when no process is yet associated
with buffer. But it is not the case.
Some more context:
(full thread is in

These are two R blocks that should be associated with two different ESS
R processes.

When we edit the first block and when no ESS process is available,
`ess-eval-line' respects `ess-gen-proc-buffer-name-function' set by Org
mode, and creates a new ESS process "foo".

But when the "foo" process is already running, despite different
`ess-gen-proc-buffer-function', `ess-eval-line' connects to the existing
"foo" process rather than "*bar*", as we anticipated.

The only workaround, which is not ideal, is to start ESS process
unconditionally. We'd like this to change.
