Testimonial selection

Is it possible to show a random selection of two testimonials on the front page? I’d love for the testimonials to rotate through the available content; but I only see the option for it to show the most recent two posts. I know this is possible with the testimonials shortcode, but don’t see an option to choose the display order within the Dara theme.

In case it’s relevant, I’m actually working to transition this to a self-hosted site where I can modify the CSS; the link is just to an initial test version hosted on my free account.
