Creating an event without using delegates

I currently have an event with the tag ‘BlueprintImplementableEvent’. If I open the level blueprint and right click on the blueprint, I do not have access to this event. I need to go to the Functions tab on the left, click on the override dropdown button and implement the function there.

I want my event to act like the “OnActorBeginOverlap” event. This seems to use a macro that defines a delegate. Is there a way to have an event show up on the blue print event graph without having to declare a delegate?
