Randomize slides shown by Featured Slider

Is it possible to randomize the slides shown in the featured slider? On our home page, I do not always want the slides to be shown starting with the first slide. Every time someone visits the home page, I would like the order of slides to be randomized, or at least start on a random slides. If there is no way to set the slider to randomize via the GUI, is there an easy change somewhere in the code where I can pull the slides and perform a PHP shuffle() on the array of slides to be shown? Thank you.
