Cinemachine for 2D game

I tried Cinemachine and it works like a magic for 3D games! Awesome!

But for my 2D game it is not suitable out of the box.
In my game I need orthographic camera to not follow player on X axis, but to follow him on Y axis, but only on the way up, when the player is around the center of the shot, and if the player goes down the Y axis, camera shouldn't follow him (see attachment below).
I couldn't done it out of the box. Or I couldn't find a reasonably easy way to do it.

I think Cinemachine lacks a thing essential for almost any 2D game - Dead Zone Width and Dead Zone Height for Body.

 

I'd just like to second this. Adding a dead zone (and the opposite, I'm not sure what you'd call it but a distance beyond which damping is ignored to guarantee the character stays on screen even when moving quickly, what I think the red zones on the Composer are?) to the basic Transposer would be a huge boon for 2D games, especially platformers.
