Okay so I have found a few things out. Looks like using the SpringPanel.Begin(GameObject obj, vector3 pos, float strength) produces the best results, although it takes a little tweaking so here is what I did.
For the gameobject I passed in the ScrollView, the Vector3 has the x position of the scrollview y position of the scrollview + the specific menu item's y position and 0 for the z, then strength just some value.
