Notify Observer Missing on Decorators created in Blueprints

When creating your own decorators, you’ll need to set 3 variables in the constructor in order to enable the “aborting” dropdown you’re looking for. I’ve used the following constructor when I wanted to have a “Does Path Exist” decorator that would abort the underlying tree when it failed:

UAI_DoesPathExistAborting::UAI_DoesPathExistAborting(const FObjectInitializer& ObjectInitializer) : Super(ObjectInitializer)
{
	bAllowAbortLowerPri = true;
	bAllowAbortNone = true;
	bAllowAbortChildNodes = true;
	FlowAbortMode = EBTFlowAbortMode::None;
}

I don’t believe that it’s possible to do this via Blueprints, so you should have to use c++.
