Question Number

Hello,

   I can't find the "hide/show question number" setting available in my forms. I've read it could still be in rollout for some. 

My question: I have a form with optional questions and ramifications. If a user "jumps" to a certain question, the question number changes accordingly to the number of questions the users is completing. 

I wish to have a numbering fixed for all users, regardless of the user answers so that a certain question has always the same number for each user. 

Is it possible?

Thank you.

Andrea
