Hey Senzacija,
There isn’t an option for that in the shortcode but I’ll see about adding it in a future update. In the meantime, if you’re comfortable with code, you can add it manually. In includes/shortcode-slider.php starting around line 67 you’ll see the js inline for flexslider. Here you can add additional options from the flexslider API.

So in this case you would add animationSpeed: 600
. The 600 is in milliseconds.
// Load Flexslider API
$shortcode_output = '<script type="text/javascript">
jQuery(document).ready(function($) {
$(\'#bne-slider-id-'.$slider_random_id.' .bne-testimonial-slider\').flexslider({
animation: "'.$animation.'",
smoothHeight: '.$smooth.',
pauseOnHover: '.$pause.',
controlNav: '.$nav.',
directionNav: '.$arrows.',
slideshowSpeed: '.$speed.',
animationSpeed: 600
});
});
</script>';
Note that the last item does not have a comma at the end.
