Scheduled reports: per-report "E-Mail Reply-To"

Reports now have an optional "E-Mail Reply-To" field on the report config form, so replies to a report's emails go to the address you choose. Enter one email address, or {ACCOUNT_OWNER_EMAIL} to use the account owner's email when the report is sent. It works without a custom SMTP configuration. Leave it blank and the report keeps using the Reply-To from your SMTP configuration, if one is set. In report bulk management, the "Email Reply-To (optional)" CSV column sets it for many reports at once.
