JQuery :: Select A Div Dynamically And Then Keep That Selection While Moving Within The DOM (passing A Target Path)?

I built a reusable plugin for slideshows. Client now needs me to add something that will affect its reusability.The line below is a snippet which is attached to a nav button. Each slideshow has a dot per slide. When clicked I get the number of sibling that it is within the group and then I look UP the DOM to the nearest div with the class called 'slide_holder'. I then display the slide that has the same sibling number as the dot(In other words - If you click the second dot in the group of dots, then the second slide will fade in. If you click the 3rd dot, then the 3rd slide will fade in)Below is a snippet (CLICK HANDLER)

$('.slider_dot').click(function() {
$(this).parent('.slide_dot_holder').prev('.slide_holder').children().fadeOut('slow');
$(this).parent('.slide_dot_holder').prev('.slide_holder').find('div:eq(' + $(this).index() +
