Answerlist with two columns only on specific questions

Question

Is there a way of specifying an answerlist with two columns directly in the .rmd question?

I am preparing a single choice pdf exam using R exams exams2pdf(myexam, n=1) with answer lists containing either only texts or only images, and I would like to make some questions with the answerlist in a two-column layout (e.g. only questions that contain images). I've seen the possibility of changing the template, but that would change the layout for all questions.

  ```{r, echo = FALSE, results = "hide"}
     exams::include_supplement("a.jpg")
     exams::include_supplement("b.jpg")
     exams::include_supplement("c.jpg")
     exams::include_supplement("d.jpg")
  ```
