ie understand how to put the intermediate time is not forbidden.be grateful for the answer

No. Impossible. Mode only 2 . They don't change. Choose the one that is needed if less time is needed, just unplug and remove the clip.

probably, not precisely expressed,sorry.the question was whether it is possible to set the intermediate time of the session, between 20 and 60 minutes,or strictly 20 or 60 minutes,without any previous shutdowns.now it is clear,so you can do.
