When you mass create objects you can specify a prefix and suffix that are added to the created object name. The prefix is added before the name and the suffix is added after.
For example, you have six offices in Building B. Every office has a temperature sensor that you want to log with an interval trend log. The sensors are named Office x, where x is the room number. When mass creating the interval trend logs you add the prefix Building B, and the suffix Interval Trend Log. Building Operation creates the interval trend logs and names them Building B - Office x - Interval Trend log, where x is the office number.
