The illogical design lacks clear official documentation
Are you sure?
While I do agree that it's somewhat of an unintuitive design, it has been improved since the last time I encountered it. Because nowadays you can add animations to a sprite dynamically. Meaning you can:
1. Create your 4 sprites
2. Create animations on each (A, B, C, D)
3. Set them to use that animation
4. Load your image into each animation respectively
That should do the trick.
