Custom Report Group Data By = VIA

We would like to be able to generate a report by how tickets are submitted.   For example, I would like to create a report (most likely under custom reports) that will show ticket count and group data by VIA values.  My upper management would like to be able to see how many tickets are entered by the different ways possible. (i.e. Email, Pop Form Widget, Phone, Live Chat Widget, In Person, and WhatsApp)
