How do I setup nested components in c++

So what I’m trying to setup is basically a USceneComponent that I can add with the ‘add component’ button in blueprints that comes with a UStaticMeshComponent already attached. Not sure that this is possible but it seems like it should be.

Here’s the relevant part of the class:

UCLASS(Blueprintable, meta = (BlueprintSpawnableComponent), ClassGroup = CustomGroup)
class UCustomComponent : public USceneComponent
	UCustomComponent(const FObjectInitializer& ObjectInitializer = FObjectInitializer::Get());

	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "Custom")
	UStaticMeshComponent* CustomMesh;

And the constructor:

UCustomComponent::UCustomComponent(const FObjectInitializer& ObjectInitializer) : Super(ObjectInitializer)
	CustomMesh = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("Custom Mesh"));
	if (CustomMesh)

When I add UCustomComponent to a blueprint it doesn’t show anything nested. In the details panel I can see properties of both components but I can’t tell which is which 'cause they aren’t categorized. Also, it seems like they’re using the same transform as changing one affects the other.

Same problem, did you find a solution ?
