Is creating custom animations/poses within Sequencer possible ?

I’d like to know if creating custom animations/poses for Skeletal Meshes within Sequencer is possible.

I’d love to know this too. If I could do all my animating within Unreal it would make UE4 my primary animating interface and you could easily create and export movies. If it’s not possible I really hope they are considering it since UE4 seems to be outgrowing it’s original intention in just building games and more of an overall 3D platform.
