The user should be able to select multiple events at the same time by pressing the control key. At the moment this can not be done.
The following example shows the issue: http://dojo.telerik.com/udItE -> It is not possible to select events from Meeting Room 101 and Meeting Room 201 at the same time.

This feature would make it possible to swap events from different groups. For example, swap the meeting rooms of two events.
