I want to give the spline point an animation in the sequencer.

I’m making videos with Unreal Engine.
Currently, I made Niagara FX using Spline.

I’d like to give the Spline points a keyframe in the sequencer, but I don’t know how.

I saw the location information according to the index of each spline, but it was in the event graph.
I don’t want a way like an event graph that I can see only when I use Game Play. I’d like to check it out on the viewport right away.

Is there any way?
