Save and Finish Later - Ticket Functionality

Hello,

Is there a way for clients to save their partially completed forms (ticket requests) as they complete tickets to be finished and submitted later?

If not, is there a possibility of this feature being developed? Our form is roughly 230 fields to complete and we would benefit greatly from the ability to save and finish work at a later time.

Lastly, what are the parameters for the system timing out. We have received error messages or the greyed out x next to the person icon but no "warning' message indicating a time out will occur soon. From my research, I cannot find a time confirmation. Our users have expressed frustration over not knowing how long they have to successfully complete the form before they are hit with various error messages.

Thank you,

Missy
