Really very sorry, but I moved the topic here and it's somehow vanished!
Anyway, I made you a small vertical slider in knobman. If you've never heard of knobman, it's a great little free utility to make your own sliders and knobs. You can get it here: http://www.g200kg.com/en/software/knobman.html.
I've included the knobman file so you can see how I made it.
To get the slider into SM you need to drag in an animated knob from the toolbox, then click on the properties and go to 'load animation' and choose the image that you have exported from knobman (Use .png files because they allow transparency).
