This is a solution that may help to get a neutral to a smart switch in a location that didn't have a neutral originally without having to pull any wire, this is just a possible solution, obviously you need to verify local electrical code requirements, ensure that configuration doesn't cause other circuit load issues etc. but it's an idea that could help - use this idea at your own risk !
