Custom Random siders

is there is a way to use 2 different sliders at a time, that could be a solution…

One slider (for example, slider B)could be all testimonials on shuffle mode, and the other slider (slider A) could be ball banners in order. Then rotate between slider A and B after each slide? I’m not sure this would work, but it is a solution like this that we need to think up. Maybe other plugins offer a way to randomize some slides and make some static.

To better represent what the client wants see below:

#A =Testimonial Slide (Randomized)
#B =Ball Slide (Static)
