Can Unreal Engine Dataflow Assets Use Vertex Colors for Cloth Constraints Instead of Manual Painting?

I’m working with Chaos Cloth in Unreal Engine and using the Dataflow Cloth Asset system to turn a Static Mesh into a Cloth Asset. Instead of manually painting the constraints with the brush tool, I want to use pre-imported vertex colors from my 3D software (Houdini) to define pinned and dynamic areas. My vertex colors are already visible in Unreal (e.g., Red = pinned, Black = free cloth).

Is there a way to access and use vertex colors inside Dataflow to automatically set up cloth constraints? If so, what nodes should I use? Or is manual painting the only option at the moment?
