If you look inside `org-beamer--format-block', it uses
`org-beamer-environments-default' and `org-beamer-environments-extra' to
format the blocks. See docstring for the latter for details.
The code responsible for LaTeX block generation is
(when (nth 2 env-format) ; when we non-column block
(concat
(org-fill-template ...) ; opening \begin lines
contents ; block body
... ; block closing \end lines
)
org-fill-template is using the template from the
`org-beamer-environments-*' replacing %-chars as described in the
docstring.
In order to handle CUSTOM_ID property, you can
(1) Introduce a new %-substitude to be handled in org-fill-template
call. It will insert block ID. (for example, using
`org-beamer--get-label')
(2) modify `org-beamer-environments-default' to insert label
appropriately.
Patches welcome!
