Is is possible do Group By Query Reports like you can on Custom Reports? I have wrote a Query Report to replace an existing Custom Report for Pending Requests to give more control over how the data is formatted. For example only displaying a portion of the description instead of the whole thing. 

However, it doesn't appear to let me Group By Request Status because it want's all the other fields being selected in the included in the Group By, which is not I what I am looking for.  Is this possible in query reports?
