UStaticMeshComponent In 5.5

In 5.5, 'bDisallowMeshPaintPerInstance' is no longer a member variable of 'UStaticMeshComponent'.

Is there a replacement? Has the variable been removed? Bug?

I don’t see it listed in the documentation:

More specifically, this code results in an error:

UInstancedStaticMeshComponent* TargetComponent = nullptr;
TargetComponent->SetStaticMesh(Component->GetStaticMesh());
TargetComponent->bDisallowMeshPaintPerInstance = true;

VS Error:
‘bDisallowMeshPaintPerInstance’: is not a member of ‘UInstancedStaticMeshComponent’
