How to animate a street light gets cut in half by a sword in Sequencer?

I’m making an animated short film, and the animation is imported from Blender. There is a scene featuring a character with rather large breasts jumping from a portal in mid air and landing on the ground.

In order to achieve the breast bounce physics, I used Anim Dynamics nodes in that character’s AnimBP. However when that AnimBP is played in Sequencer, dragging and moving that animation bar has no effect on when that animation starts and end like it would with an animation sequence.

You might wonder why don’t I also just use the animation sequence of this character, that’s because the Anim Dynamics effect will only show when the movie is rendered if I inserted the animBP in the sequencer, animation sequence on the other hand will not carry the effect of Anim Dynamics in the rendered movie.

So I thought to use nodes in a blueprint in conjunction with the Sequencer so that I can control the start and finish time of that animation with the breast physics shown in the rendered movie.

Thanks.
