How to create a C++ struct that behaves similarly in Blueprint to Vector with inlined textboxes like "X:[0.0] Y[0.0] Z[0.0]"?

Heyo I was wrong.
I missed a block of code that allows users to inject custom factories for graph pins :

You can register new factories like this (preferably during engine/editor initialization) :

FEdGraphUtilities::RegisterVisualPinFactory(MakeShared<FTestPinFactory>());

I just made a snippet with a full working example, with a struct containing a string and an integer, and made the two fields editable directly within the node.
Sample struct :

USTRUCT(BlueprintType)
struct FSomeStruct
{
    GENERATED_BODY()
    UPROPERTY(EditAnywhere, BlueprintReadWrite)
    FString Str;
    UPROPERTY(EditAnywhere, BlueprintReadWrite)
    int32 Int;
};

Sample function

UFUNCTION(BlueprintPure)
static FSomeStruct SelectSomeStruct(FSomeStruct A, FSomeStruct B, bool bPickA)
{
    return bPickA ? A : B;
}

Result
