Feature to pause and stop a section in a test

My idea is that users are able to stop a section after initiating it. After completing three sections (time consuming), accidentally starting a new section is very frustrating since it is impossible to stop the countdown. It happened to me and I had to go through the questions again to get to the last section. Sometimes you may also initiate a section but then realize you do not have the time to finish it for some reason. Perhaps a button could be made to lock and unlock the feature so those who have a hard time with time pressure don’t panic and pause it. It should only be possible to pause or stop it if it is due to external problems. I think it would be great and would like to see this feature implemented!
