Slider on mobile doesn't "multiple-item swipe carousel"

[kukovisuals]

Issue description:
I've been digging into the documentation and can't find a way to have a multiple-item swipe on mobile the touch slide only supports one item at a time

Demo link/slider setting:
var sliderBestSellerTwo = tns({ container: '.pcsContainer-carousel-two', items: 1.5, loop:false, controls:false, mouseDrag: true, speed:500, gutter:12, navPosition: 'bottom', autoplay: false, autoplayButtonOutput:false, slideBy: 3, swipeAngle: true, responsive: { "1024":{ items:4, speed:800, gutter:30, } } });
