Expiration Webhook - missing critical fields

It's great that we can send expirations to a webhook, but with the available variables it isn't quite complete. I don't understand why the asset ID and expiration ID aren't passed by default. If the asset has more than one expiration, as there's no way to determine which one it is. Sure, I can pull the expirations and filter based on the date, but that just adds extra api calls and processing. Adding the asset ID and expiration ID would be extremely helpful here.

Thanks
