Slider Revolution - Hide Thumb inside navigation Thumbnails

Hi people,

I need some help with my project. I am doing a full screen slider with 12 sliders and a footer navigation Thumbnails and all is doing fine but i want one of that slide to be hidden in the navigation and not show on the thumbnails. The reason i need this is because I need that this slide that is hidden show only when i click hover a static layer. In the hidden slide is gonna be a form for contact information. How can i hide one specific slide on the navigation and on the Thumbnails?

Thanks for your support.
