What about #+attr_yourbackend ? E.g.,

  #+attr_yourbackend: :type mct
  - answer a
  - answer b
  - answer c

or,

  #+attr_yourbackend: :lines 2
  #+begin_answer
  This is an answer.
  #+end_answer

Another, more advanced option, is to use a parse tree filter to create
pseudo-types, i.e., element or object types that don't exist in regular
Org syntax. See `math-block' type in "ox-latex.el", in particular
`org-latex-math-block-tree-filter'.
