How can I track which question users are dropping off at?

I have not seen a clear answer about how to track what questions users are dropping off at. This would be very helpful in order to know which questions have high friction points to increase conversions.

With a 12 question cards form, I'd love to know which question # incomplete submissions make it to. 

Is this possible, and if so, what specifically must I do to track this?

Unfortunately, we don't have a feature or a third-party integration to track where the user dropped off the form.
