Anim node OnCeaseRelevant?

This method seems to have been present back in UE3 but is gone in UE4. We’re doing something similar to montages where it’s important to let the gameplay side know that the node playing the triggered animation has been blended out; currently we’re manually tracking the relevant nodes, and firing off our own call when one stops being relevant. Seems a bit sketchy. Is there really nothing in the engine for this?
