In WorkStation, you can mass rename all objects that are possible to move. For example, you can rename alarms but not properties.
You can rename the objects one by one. You can also copy row-separated text from a file, such as an MS Excel file, and paste it to rename several rows in one single operation. When you paste, the copied text is pasted from the row you have clicked and down in the list. If the copied text is longer than the number of rows, pasting stops at the last row.
When you hover over the names in the Name column, the full path of the object is displayed.
