Is there a PickupActorInterface for c++ actor?

Does anyone have, or know how to create, an equivalent Interface in C++ to the PickupActorInterface blueprint? I created an actor in C++, later I found that it has to be moved around. As I understand it, I can’t add a blueprint interface to a C++ class, right? I probably can convert the C++ actor to a blueprint, but that requires major refactoring. Hoping for a simpler solution.
