Gravity Forms Skip Required Fields

Hi all!

I have a quick question about using gravity forms on wordpress. A client we are working for has large indepth forms, some are 10+ pages of lots of info. One of their requests is to be able to skip past sections to fill out other sections, as users will be able to come back to the site later and finish the form before submitting. But if they get to a point in the form where they do not have the info to fill out but it is required, the client wants the user to be able to skip this and move on to another step, the problem is we need to ensure they come back and fill that out before they can submit.

Any thoughts on how this could be achieved? Ive search for some sort of plugin / add-on for GF but haven’t had any luck.
