Improvement of the stop oversleep feature

I use typed math (stage 4) to get my brain going and I feel like it would be better if I could choose the level of difficulty and the amount of calculations required to stop the alarm, as 4 of stage 4 are too easy for me, but there’s no way for me to solve 5 stage 5 in time for the arlam to come back. I feel like if I could choose 2 of stage 5 that would be perfect.
