Bookmarking a page using a button

We are working with a service who are developing a ‘support tool’ which displays information to the person completing the form based on the answers they have provided. They are wanting to explore if it possible for the user to be presented with a ‘bookmark’ button to preserve the information so they can review it at a later point.

Appreciate this might be complex for a number of reasons (different browsers, how long we’d need to keep data for and how we’d expire this etc) but is this something that anyone has done before and if so is it functionality we have OOTB?

Will they be logged into netcall?
If they are, you could Save the partially created form, and they can revisit using the portal case view.

No, they wouldn’t- they’d be a member of the public viewing the data on a webpage
