Currently WordPress doesn’t allow you to add custom bulk actions. See codex. Adding them is super easy with this plugin.
This is based on solution found here: http://www.skyverge.com/blog/add-custom-bulk-action/ 
This plugin just makes it more easier to use.
Plugin adds a class named Seravo_Custom_Bulk_Action which you can use to easily define custom bulk actions. 
See documentation and examples here: https://github.com/Seravo/wp-custom-bulk-actions/
