Extend schedule to show hours after midnight

I would be happy if I could set the schedule across days.

I have ADHD and find it very difficult to maintain a regular sleep schedule.

Example.

Regarding sleep time, I would be happy if I could set the time from the night before to the noon of the next day. Also, I can't adjust my wake-up time to suit my schedule. Therefore, it would be very helpful to be able to time-shift my schedule after waking up in the morning. I would be happy if there was a list setting that would allow me to enter two or three slots in prepaation, rather than just the minimum lot when time-shifting.
