Default value for TArray properties

If I have a TArray property how can I specify the the default value in MakeStruct blueprint node?

USTRUCT(BlueprintType)
 struct FMyStruct
 {
     UPROPERTY(EditAnywhere, BlueprintReadWrite, Category=MyStruct)
     TArray<FVector> MyArray;
 };

In my blueprint node Make MyStruct I must connect an array to MyArray.

Is it possible to make MyArray default to an empty array, so that I don’t need to connect an array to MyArray in Make MyStruct node?

I have tried meta=(MakeStructureDefaultValue = "{}") and meta=(MakeStructureDefaultValue = "TArray()") but it does not works.
