Show deep sleep duration while tracking

if I’d wake up while during the night I’d like to see how long I’ve spent in the deep sleep phase. That’s because sometimes I have a not-regular sleep and wake up in the middle of the night and can’t fall asleep again. Sometimes I realize the day after that I had already slept 4 hours in deep phase and that’s enough for my average night, if I’d know that before I’d avoid to spend the rest of the night laying awake in my bed trying to sleep again.
As already asked on this suggestion (link) but at least I’d love to have just a second clock visible while tracking (I think that’s easy to program for now)
