In ClearQuest Web 7.1 and 8.0, it was only possible to perform simple modifications to multiple records. The feature now has several improvements, including the ability to perform state transitions on multiple records. You can find the demonstration of these changes in the download list for the ClearQuest Open Beta.
This feature is still in development, and your feedback is appreciated to help with improvements. See ClearQuest Open Beta Support for info on posting feedback or questions. Keep in mind that ClearQuest 8.0.1 is in beta and is subject to change. See the open beta website for more information on the program's terms and conditions.
