Set an alarm to go off after you've been a sleep X amount of hours

I have ideal sleep and all, but I’m an insomniac. Just because I go to bed at 10 doesn’t mean I’ll be asleep by 10:15-10:30 sometimes I can be awake for hours just laying there. On days where I don’t have to be anywhere or I want to take a nap it would be cool to set a sleep detection to go off after I’ve been asleep say 3 hours instead of 3 hours after i hit the nap button since I’ll likely still be awake.
