[Plugin: JJ NextGen JQuery Slider] Different effect when prev button clicked

Hi – on my slider I have my effect set to ‘slideInLeft’. It would be nice for the effect to be slideInRight when the previous arrow is clicked, as if the page is being slid back again.

Is there any way to do this? Please let me know. Many thanks 🙂
