The Reminder widget shows all tasks, not just the ones for today

Is apple planning on making their “Today” to-do list customiseable? I’m asking because when I have the reminder widget, with a list that is customised to my liking, it shows all tasks, not just the ones for today. The problem I have with the “Today” list is that it doesn’t fit the overall aesthetic of the rest of my homescreen.
