Slider control in PTC MathCAD PRIME 9.0

I'm converting a MathCAD 15 worksheet to Prime 9.0.  The MathCAD 15 worksheet uses sliders to control input variables for a design.  The slider in MathCAD15  is installed via insert/control/slider.  I do not see anything similar in Prime 9.0.   Am I missing something -- are there any options?
