Copy Sliders so they are linked to Same Variable?

I have a course that has a number of sliders on each page.

Each time I copy or duplicate a page with the sliders all the elements (including the sliders) are copied - YAY

BUT on each new copy the sliders are linked to a new Variable (i.e. Slider1, Slider2, Slider3 and so on...)

Now I can manually reset each slide BACK to the original variables on the source page - but that's a pain

Is there a way to copy a slider and have it copy the variable it is linked to as well?
