making Sleep Mode time setting permanent

i use audio books to help me sleep. it would help a lot if the sleep timer setting did NOT get zeroed out when the device turns off.

the power setting stays in the fuze memory even after the device is turned off, why can’t the sleep setting ?

what i want to do is set the sleep timer to 10 minutes (or so), then try to go to sleep - if i do fine. if i don’t then when the fuze shuts off all i have to do is turn it back on and continure listening. repeat as necessary.

the way sleep mode is now, every time it stops, i have to go to settings and reset the sleep timer, that wakes me up more than the way i suggest.
