Is there a way to configure Inbox hierarchy to flat, chronological order?

This might have to do with plan limitations, but is there a way to configure the Inbox to display notifications in a truly flat chronological order?

I know I can probably archive notifications and just keep less on my Inbox “plate,” but, with it being broken down by project & task, once you get a decent build up of notifications, it’s difficult to see which ones are the new ones, as you have to go fishing through the different projects and tasks to find what is truly the latest notification.

Is this not available? Or is it a premium feature?
