Multiple selection/multiple deletion of selected items

I would like to see a feature that allows us to select multiple items for eg multiple expired tasks and be able to delete them or archive them all at once. This feature should be applicable across the board. To allow us to edit or clear large amounts of data quickly. In my case I have a large amount of expired tasks that I want to archive or delete. The current way to achieve this is to go through and delete each task 1 at a time. That is not very user-friendly and is very time consuming. Therefore I would like to see that implemented. Or a way to clear all my data without deleting my account.
