[World Partition] Anyway to know if a cell and all objects within a cell has finished loading/streaming?

Does anyone know of a way to see if a cell in World Partition has successfully loaded/unloaded? I couldn’t find any events to hook into for this.

Most I can think of is creating BP actor with an event that gets fired on Begin Play, manually placing these actors over every cell, and then creating a manager that listens to these events. This feels really hacky and unreliable. I am wondering if there is a more integrated way to achieve this.
