In the model view, box over the items you want in a specific Zone, right click/properties, give them a zone name.  Do the same for the other zones.

Go to the item list, & sort that list by item zone.  look for the ones that do not have any...go to those items and label them with the correct zone accordingly.

Export the item data to a csv file & open it in Excell.  Make a pivot table from the data, & sort by Zone.
