Empty Trash/Archive from Smart Folders

I’d like to be able to “Empty Trash” from the Trash Smart Folder, and “Move to Archive” from the Unread Smart Folder. Otherwise, trash has to be emptied individually by account, or else one-by-one (or select all, then delete) from Smart Folder Trash, and you have to move from the Unread Smart Folder to the Inbox Smart Folder, to “Move to Archive”.
