Set Date/Time for Task to Automatically Move To Another Category

We currently have our categories (in part) set by priority, what's been delegated, what's "next up", etc.

It would be really helpful to be able to set a date and time where a task will move itself back to the Priority Category.

I know there are due dates and reminders but with a very full task board, things get lost in the mix rather easily.

This is a separate thing, but just to ++ the idea, copying or moving tasks between boards and duplicating tasks would be incredibly helpful as well!
