Bind/ Merge all rev sliders into single slider worpdress?

I am using rev Slider plugin in WordPress theme. I have different role in a wordpress. Each user of different roles create the slider from admin panel of WordPress. Now the problem is to show all the sliders created by different user into a single slider.In front side, there will be a single slider where all slides will be rotated. All the sliders created by different user will be merged as a single slider. How to implement this? Please help me out to solve this requirement.
