We use an AD attribute to manage user types.  For example, under employeeID, we have a designation called "C1" which stands for a Non-Employee.  Every C1 in our domains has this attribute and we have a requirement that every one of these accounts must have a manager.  I want to run the Users Without Managers report on a daily basis and only report on C1's, meaning I want to use the value in this attribute to generate the report and do not see any way I can accomplish this simple task.  Is there any way I can use a filter or modify the value to select on this report?  I currently do this today using mPowerTools by Namescape and want to replace this by using ADManager Plus.  Any suggestions would be appreciated.

Thanks
