How do I import svg images as grease pencil keyframes?

Im having I really hard time figuring out how to do this. Im exporting frames as svg from moho (cant export it as an animated svg) and I want to import it into Blender.

It imports them as separate objects all having 1 frame on frame 1. I can merge them, and they will all be on separate layers but I want them all on their own frame. While yes i can just move the frames manually, but when you have an animation that has 100+ frames its not really doable.

What is the best way I can achieve what I want? Is there a tool that can easily offset frames on different layers? Or something in geo nodes (I attempted to do something in gn but it would never be able to apply it)
