Voronoi fracture into alembic. How to transfer the selection tag?

Hi,

I need due to performance issues, to cache the whole dynamic simulation of a Voronoi Fracture into alembic file. The problem is the selection tag of the Voronoi can’t be cloned; I think the reason is because it’s generated dynamically frame by frame.

My guess is there should be a way to transfer this data frame by frame with xpresso, any ideas?

Thanks
