Set mesh dimensions in collision radius for multiple meshes in Niagara?

So, I’m just toying around with the PBD/Advanced Niagara Content Examples, and I’ve been trying to make it work with multiple meshes in the mesh renderer. I have the meshes in place, but I need to adjust the mesh dimensions/collision radius per each mesh. Since the initial mesh dimensions/collision takes only one vector, I figured applying a scratch input where I can access the Mesh Index Particle Attribute and set vectors/dimensions dynamically might be the better way to go about this. The issue is I don’t know where to go from the Map Get/Mesh Index part.

Not sure if I’m asking or approaching this the right way since I’m a novice in Unreal Engine. If I’m overthinking this and there’s a simpler solution that I’ve overlooked, please let me know! Thanks in advance.
