Consider the following example:
#+begin_src org ,#+title: Test ,#+options: H:2 ,* Section :PROPERTIES: :CUSTOM_ID: section :END: ,** Frame :PROPERTIES: :CUSTOM_ID: frame :END: ,*** Block :PROPERTIES: :CUSTOM_ID: block :END: #+end_src If I export this to Beamer, then both section and frame get appropiate labels, (either with org-latex-prefer-user-labels set to t or nil), but the custom_id for block is completely ignored. I want to use theorems as blocks in frames, so it would be very useful to me if the custom_id in the block is exported as \label{block}. Is there a way to have this by setting a variable, or something? It works if I include #+beamer: \label{block} below the properties drawer, but I would prefer not to duplicate the label, of course.
