Hi! For my survey, I have 5 questions that I want the participants to be able to navigate in-between. So, I added a "previous page" button on these questions. However, I also want to record the time spent per question. This timer has to stop when a previous or next question will be visited, but when the participant comes back to the same question, the timer needs to add the additional time and not start over. How do I install this?

I hope someone knows this :)
