Redo or undo answers in an unsubmitted Forms

Hi all,

We use several forms on which our employees can indicate which consumables they wish to receive. But we run into a problem when they have ticked a number of options and decide not to submit the form, the next time these items are still ticked and it is not possible to remove them again. They have to submit the form first before they can start with an empty form. 

Also, if they accidentally select a wrong option, it cannot be changed until they have submitted the form and can start a new form.

Is there a possibility to undo or redo the form from all fields that are ticked or filled in?

Thank you in advance
