UMG Scroll Box speed tune for mouse wheel

Hello, I want to request a small improvement for UMG Scroll Box.

At that moment we can`t adjust scrolling speed with mouse wheel. Because it is constant in

/** How much to scroll for each click of the mouse wheel (in Slate Screen Units). */
const float WheelScrollAmount = 32.0f;

Please add a property for adjusting that amount. Thank you.
