Display Time Until in "days" only (not months/days)

I’d like the option to have the Time Until app display only days (or days/hours), which feels more like a real countdown to me (“I’m counting the days till…”).

For me, saying “MLB Opening Day is in 3 months, 1 day” is more abstract, less tangible (and less fun) than saying “MLB Opening Day is in 91 days”, and watching that same big number tick down, day by day.
