Flexslider - 每张幻灯片上的不同幻灯片动画

Question

我现在使用此代码更改每张幻灯片的速度，但我还需要更改某些幻灯片的幻灯片动画。有任何想法如何以类似或任何其他方式做到这一点？

    $(window).load(function() {        
$('.flexslider').flexslider({
    animation: "slide",
    controlNav: false,
    directionNav: false,           
    pausePlay: true,
    animationSpeed: 300,
    start: function(slider) {
        clearInterval(slider.animatedSlides);
        slider.animatedSlides = setInterval(slider.animateSlides, YOUR_TIMEOUT_FOR_FIRST_SLIDE(ONLY FOR START));                
    },
    after: function(slider){
        if(slider.currentSlide == 0) {
           clearInterval(slider.animatedSlides); 
           slider.animatedSlides = setInterval(slider.animateSlides, FIRST_TIMEOUT);
        }
        if(slider.currentSlide == 1) {
           clearInterval(slider.animatedSlides); 
           slider.animatedSlides = setInterval(slider.animateSlides, SECOND_TIMEOUT);
        }
        if(slider.currentSlide == 2) {
           clearInterval(slider.animatedSlides); 
           slider.animatedSlides = setInterval(slider.animateSlides, THIRD_TIMEOUT);
        }
    }          
});
