It looks like on April 17 Smartsheets changed the "From" address for automated alerts from "Smartsheet Automation" to the spreadsheet owner name.

This has caused a lot of confusion for our team. Is there any way to change the "From" sender for messages? Perhaps it could be specified in the alert settings? That would be awesome.
