Customize Animation distance

Hi, first of all thank you for this nice plugin, really helps speeding up the animations of blocks.

I often use fade + direction animation and from what I see in the CSS there is a default translation value for each, for example fade-up will have:

transform: translate3d(0, 100px, 0)

Sometimes I would like to have blocks with a more subtle animation, something closer to transform: translate3d(0, 50px, 0) and I end up doing a lot of classes to tweak that distance.
Would it be possible to have an additional setting in the UI to customize the value directly from the editor?

Something that would look a bit like this:

I realize this is more of a feature request than a support request but I would be a great addon.

Thanks again,
Alessio
