How can I sort Planner tasks within buckets by due date automatically as I add them?

I use a Kaban-style board sorted into buckets for each project. Frustratingly, I cannot figure out how to sort the tasks within a bucket by due date automatically. Currently, if I want to see the most urgent items at the top and least urgent at the bottom, I need to manually drag the task down... which does not scroll down well, so I often need to drag & drop, drag & drop, drag & drop... until it arrives where I need it.

How could I keep this same Kaban-style board format (not list, grid, or schedule view) and have each column sorted by due date, even when I add a new task in?
