Ihavn't worked too much with the scrollBar, but I think I have an idea of what you want, though I'm not very sure if it might work.
Can you try to add a Move effect to the panel containement, and at each effectEnd, set the verticalScrollBarPosition at currentPosition+1 unit (I understood correct, and this is what you want?)
Also, at each effectEnd event, you could restart the move effect, and so on, until the position of the verticalscrollBar is at the end.
If you want to keep it simple and can do without the scroll bars, just use a timer and change the y or top property of the Canvas, with increasing negative values.

implement a simple MOVE effect - from/to (or yby)/duration properties would depend on the size and readability while moving; i think you will figure it out.
I figured it out. I was attempting to change the y position of the inner canvas by mistake. I needed to change the y position of the OUTER canvas.
Thanks for your suggestions.
