Adding an item to an existing order is the mechanism for the daily "a customer wants something that isn't in their pull yet" requests — walk-ins who grab something off the shelf, phone-ins who ask you to set a variant aside, replacement copies for a damaged sub. The action reserves a copy for the customer using the same underlying logic as weekly check-in, so everything downstream (invoicing, fulfillment, restock, reports) behaves normally.
Add Item only works with items Manage Comics knows about — i.e., items added to your system through Manage Comics (via check-in or FOC). Items entered directly in Shopify or your POS outside Manage Comics won't appear in the search.

What Happens Behind the Scenes
Manage Comics reserves a copy exactly as it does during weekly check-in. All standard behavior applies — you can remove, check out, invoice, restock, and so on.
Common Uses
Walk-in pickups. Customer browses the shelf and wants to hold a book for later.
Phone-in requests. Customer calls asking you to add something to their pull for the week.
Replacing a damaged sub. Pull the damaged copy, Delete & Restock it, then Add Item the replacement off the shelf.
