Fading In Fading Out animations?

Is there a way to define animation fade in/fade out on a per-animation basis? I want to have a general fade in for most of my animations so they aren’t snapping to each of their poses when I change one on the fly. (idle to jumping for example)

Sort of like how the source engine does it in their qc
