On occasion you may wish to globally change which engines are selected for multiple Reporter missions. For example, you may decide that you wish to discontinue promoting to a particular engine for all of your Web sites. If you had ten different Web sites, you'd have to open each mission and de-select the engine. From this screen, you can select which engines you wish to be selected, and then press the Update button. WebPosition will then prompt you to select which mission (.mis) files you wish to update. Hold the SHIFT key down to select a large group of files. Hold the CTRL key down to select multiple files, one at a time.
