Customize automatic training session stop time

Currently the automatic training session would stop 1 hour after the monotron pauses. I want to change it to 1 minutes or even 5 seconds

Hi, why is that? Are you aware that when the automatic session ends, it crops the practice time by 1 hour so that in effect it is the same if it ends 5 minutes after pausing the metronome? Perhaps we need to explain this better...
