How to trigger an event when streaming level loads?

The checkbox is under the trigger volume details in the collision settings. I’ve attached an image below showing the full description, unlike the previous image.

As for the concept it is basically what I have described. I have a interior environment so the player can be anywhere within those bounds. I will have a set of audio experiences that the player can select from a menu. I am then loading the audio ‘level’ based on their selection. As the level loads I need the correct audio file to play based on the player location and then switch between files as the player moves around the environment.

My current setup works perfectly with the exception of the start of the level. It will not start the audio file until the player moves into another trigger volume. However, I understand that the setting I have shown in the image is suppose to cause a trigger for Begin/End events at the level load. It is not working, though.
