We are redesigning an existing application in which the user has a typical master-detail view with basic CRUD operations for a certain entity type. (Actually, the majority of screens are of this type.) On one particular screen, the user has the option to select multiple entities in the master table and change two special properties for all of the selected entities in the detail pane.
We fear that new users might not find this feature since in the majority of screens it is not present. Is there a reasonable alternative to perform this sort of mass-mutation?
