Materials picker not shown for UStaticMesh property

I have component that needs static mesh as parameter.

Adding mesh as class property does not show Materials picker in Blueprint Editor



UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = Wall, meta = (AllowPrivateAccess = "true", ShowInnerProperties))
UStaticMesh* WallSegmentMesh;


Is there any way to show that?
Only way I found was to have my component inherit from **UStaticMeshComponent, **but that would not work if multiple meshes are required.

Thanks.
