Silly Qustion

I want to sort  a Jobs tables view by 2 columns

Ie First by 'Customer'

the that list odered by 'Date' in reverse

Individulaly both are easy

but I can't sort 2 headers to become one if you know what I mean 

can i group by customer and then set order date in reverse

but that means I anly see the customer name as a group and have tp click each names to see the detail

any suggestions welcomed
