Suggestion: Default Post Scheduling Time of Day

I schedule posts at consistent times so I don’t like typing in “4:00” every time, including the colon and minutes, because it never changes. Could we have a setting for a default time of day to schedule posts and only have to type a time if we want to change it? Alternatively, if it defaulted to the time from the last post I scheduled, that’d work great too and wouldn’t require adding a setting. This is just a small time save but it shouldn’t be very hard to add.
