Move Document Page to the Lost-Page Batch

 - Open NextGen® Document Management.
 - On the toolbar, select Batch.
 - In the Image Batches window, right-click a batch, and then select Set as Lost Page Batch.
 - Double-click that batch, and then on the image viewer, go to the page that you want to move to the lost-page batch.
 - On the toolbar, select the move page to the lost page  
icon, and then select Yes to confirm the move.
