Retaining variables after form submission

Retaining variables after form submission

Is there a way to retain variable values after a form has been submitted?

I have an evaluation form where a supervisor evaluates various people. I need them to be able to select a subordinate from a drop down, complete the evaluation, submit it, and then select another subordinate. The subordinate list is a lookup that is filtered, and is dependent on a previous field for the filtering. It works ow, but you need to re-authenticate each time to see the list of subordinates.

Thanks!
