Start animation on 100px above the viewport?

Hello,

Really incredible plugin, so simple to use!

I’m a bit stuck adding some sort of delay to an animation. With “animate when in viewport” is selected, it does as you would expect but a lot of the animation is missed when the image is only half visible at the bottom of the screen. Is there anyway to add some form of delay, perhaps where the animation starts shows once the icon is 100px above the bottom of the viewport?
