Check Box for All Spammers and Banned

Good day folks, I'd like to have the option to delete Spammers and Banned all a single page of listed. Just like we have the option to check mark "All" in forum page to delete or perform some other action in full sweep. At this point if you want to delete a page listed of Spammers or Banned, you have to delete one at a time. 

Thanks for your consideration
