Houdini's Particles to Blender with Alembic ( Attributes import problem )

Hi fellow blender users! Im trying to put a collection instance with geonodes on my alembic partciles that I’ve exported from embergen. With this alpha branch now I have the attributes, so I can set color, etc. for the particles, but I just cant figure out how can I pick instance fixed on the points ID-s. It seems like its constantly changing, but I hope that I just cant set it right, not another technical limitation. I’ve collected the experiences of my research in the following post in jangaforums: https://forums.jangafx.com/t/alembic-pointcloud-id-s-solved/1481/3
There are some related topics from blenderartists too, so I hope someone can help!
