I hear what you are saying here @Andrea De Giorgio. Unfortunately this isn’t an option, but it would be great if it could be considered as a feature request.
In the meantime, I wonder if you could set up an option for people to redo the VideoAsk. My thinking for the easiest way to achieve this would be adding a final step at the end with a multi choice selection. You could prompt respondents if they want to ‘Redo’ or ‘Submit’ their answers.
If ‘Redo’ is selected you could set the logic as advanced for that answer and then set the redirect link to your VideoAsk’s URL, which should force it to reload back to the start. Though, I understand this would’nt be as ideal as a back option that goes back a step and overrides the answer.
Hopefully this may help in the meantime.
