Ability to Show/Hide individual tasks on the My Work' dashboard

When in My Work, you are only able to ‘Mark as done’ in the Ellipsis options, which then hides it and all subitems from that task. Often I don’t need to see the main line item bucket, since we use Subtasks for all our actual work. I would like a way to hide those (or any specific task that I choose, really) so they don’t clutter up my dashboard, without consecutively removing all associated.

An extra functionality step would be, when hiding items, they move into their own expandable category lower down on the My Work page, so I can keep track of things I’ve chosen to hide and unhide at my discretion.

Thanks for the consideration! Upvote folks!
