To create multiple Plate Alerts using the results of a Plate Search, simply click the 'Create Alerts' button at the top of the Plate Search and follow the prompts to create plate alerts from all of the unique plates in your Plate Search results.
If you wish to delete multiple alerts at once, you can either manually select each alert and press the 'Delete' button on the Plate Alerts page or you can use the 'CSV Delete' button to select CSV filenames (created via CSV upload) or bulk alert creation actions indicated by a username and timestamp.
Selecting your relevant bulk alert creation action with the 'CSV Delete' button will delete all of the alerts created in the respective bulk alert creation action.
