USUM - Pokémon Animation Editing

[Andarkvolt]

After some digging I was able to find where the model and animation files of Pokemons are located as well as being able to view them using SPICA.
Links to posts which helped to locate the models and animation files in USUM:

After figuring out that pk3DS can unpack the animation files, I was able to swap animations around with ease. Since I enjoy having no animations for certain moves on Pokemon, I replaced certain animations with an empty file (which works fine). However a single animation file contains both the Skeletal and (Object/Material) Visibility animations. 

Main Question of the Topic: Is a way to keep 1 (Visibility Animations) and remove the other (Skeletal Animations)?

Just as an example, I'll use Ultra Necrozma: 

I want to remove the Skeletal Animation, while also keeping the visibility of the Crystal/Prism thing hidden. 

 

 

 

 

 

 

 

 

 

 

Also SPICA has a few issues for me: Import button doesn't work, it can't export animations, anyone else having this issue or know work-arounds?
