How can I get a report of asset count per customer?

Maybe I’m missing something but is there an easy way to get a list of customers and their asset/device count? Seems like this would be easy but the only way I have been able to do this is to export the entire asset list and then use excel to summarize by customer. Is there an easier way? A column on the Customer tab for this would be nice. There is a contact count column. It would be nice to also have the asset column in that same view.
