Spawn new geometry (GS) on Meshes spawn by PCG Volumes

Hi There

I Built a Blueprint for Snow Generation using Geometry Scripting. It works fine on static Meshes inside the Level. But i would like to use it on my meshes that are spawned inside my PCG Volumes. I built an Environment using multiple PCG Graphs. These Graphs use a set of Meshes.

I thought i could just assigne that set of Meshes to my BP and im good. But i cant actually assigne anything because the meshes inside the PCG Volume arent listed in the Level.

Im unsure if theres a way to work around this and still use my Snow BP on the PCG stuff.

I wanted to build a snow generator that can be used to spawn snow on smaller PCG Environments.

I attached a part of my GS BP.
