Go to the Snapshots tab within the loan application.
From here you can pick from an existing snapshot, or use the Time Machine to look into a specific date/time.
Clicking View, or the eye icon, will let you see what the loan looked like at that specific date/time.
Snapshots have a different color header to make it easier to distinguish between them and the present loan application.
Note: You cannot make changes within the snapshot. Any edits and information should be added to the loan application, not the snapshot.
