Creating Multi-stage submission Forms

Is it possible to get multi-stage form responses?

Specifically, I would like to create a form that collects submitted content at multiple stages. We need to prioritize the requested content in three stages. It would looks something like this:

***
Q1: Name (required)
Q2: DOB (required)
Q3: Rating Scale (required)

Next section

Q4: Rating Scale (optional)
Q5: Short form answer (optional)

Next section

Q6: Short form answer (optional)
Q7: Short form answer (optional)
Q8: Short form answer (optional)

***

Is it possible to capture the information based on whether or not the section was completed? Q1 - Q3 is a priority, and we don’t want to risk not getting answers to those questions if the user feels the rest of the survey to too long/burdensome.

Thanks!
