Companions

Items can be attached to other items as optional companions.  When adding the primary item to a sale, you are prompted as to whether you would like to add any of the companions. This is a time-saving feature and streamlines the sales process as the salesperson does not need to remember which items go with which.

Before you can add a companion to an Item, you must first create the companion as an Item in its own right. 

Any item can be added as a companion to another item.
