Feature Request: Disable Sleep Schedule

I can see the question has been asked but still seems to be an irritation with users.

I want to disable sleep schedule, not sleep mode, sleep schedule.

Shift worker, every day different, sometime schedule changes as the day progresses. 

I want to be able to manually activate sleep mode when I get into bed and deactivate when I wake. I know I can do this and I do, however sometimes at night if I get delayed, the sleep schedule takes over, changes the watch face and even if you deactivate it manually, 15 mins later its back in sleep mode again. V annoying.

Please add a feature where you can disable sleep schedule!!!
