Blueprint function to cast array to array of specific type?

I tried using Filter Array today to filter an array of actors by a specific type. But the Filter Array function just returns TArray<AActor*>, not the specific type I filtered by!

So I tried casting the array, but it appears that I simply cannot do this through Blueprints right now. I tried to roll my own, but got lost in a mire of CustomThunks and CustomStructureParams and templated functions and all the rest.

So I turn it over to you folks. How can I create a function that lets me cast an array of actors to an array of a specific class?
