Spine 2D animations in Unity

Hi there!
I am using spine animations for unity project.
I want to use unity animator controller to control my animations and not spine skeletal animation.
I generate mecanim controller and I get animation clips also, but when opening animations, there is not every frame visible (only first and last) I need this to use unity animation event system on certain frame.
Any help?
Or is there possible to make minor changes in spine animations in Unity Dopesheet ?

Shortly, I need my animations to be imported like this
