Looking for a way to Total a Column/Row in reports

I have a report, but I'd like to add a row at the bottom to represent the total numbers of a column. Does anyone know if this is possible?

Here is the report:

Code:

SELECT COUNT(*) AS Total FROM 'Tickets' GROUP BY X('Tickets.Department', 'Tickets.Status')

Also, is there a way to center the numbers under the department's title?

Neither is available for now, sorry.
