[Request] C++ Function easy override

Hello. I am developing a game and I am beginner on UE4.
I was confused to override at first.

If I create a C++ header file and I declare one function.
You can see example.

"example.h"
UFUNTION(BlueprintImplementableEvent, BlueprintCallable)
bool IsProcess();

Then I can override this function on UE4 .
But I have to click override button on blueprint editer.

When I put this function on event graph, I want to override this function just double click if I didn’t define this function on cpp file.
