How can I programmatically tween a Scroll View to a desired position?

I currently have a horizontal scroll view. The content of the scroll view includes a bunch of panels that are laid out horizontally next to each other. Each panel should be snapped to (or centered) when it is selected.

Currently, upon OnEndDrag, depending on the Scroll View's current velocity and positioning, the Scroll View may snap to the panel to the left or right of the currently selected panel. I do this using horizontalNormalizedPosition.

How can I programmatically "tween" the scroll view to gradually scroll towards the next panel (as opposed to immediate snapping)? Ideally, upon OnEndDrag, I would roughly decelerate from the current velocity until the Scroll View stops at the exact panel it's scrolling to. But, if that's not possible, a linear scroll to my destination x position would suffice.
