Edit SubObject Component In Graph

As of now it is not possible for me to set a UProperty of BlueprintReadWrite to a TSubObjectPtr USkeletalMeshComponent, and I’m not sure why. I would like to edit the Skeletal Mesh in the Graph Editor. The Skeletal Mesh is setup as so,

	GENERATED_UCLASS_BODY()

	/** Pawn mesh: 1st person view (arms; seen only by self) */
	UPROPERTY(VisibleDefaultsOnly, Category=Mesh)
	TSubobjectPtr<class USkeletalMeshComponent> Mesh1P;

	/** First person camera */
	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category=Camera)
	TSubobjectPtr<class UCameraComponent> FirstPersonCameraComponent;

I’d also like to access the Camera,

Thanks.
