ZOHO Invoice receivables sorting

You have many options for sorting in the receiving reports section and even allow for columns to be un-hidden so we can see the customer last name. However, I can't sort by last name when the column is un-hidden. It seems a bit redundant for me to see my customer's last name twice if I can't arrange the way in which to view by last name. I really, really need the ability to sort by whatever columns are shown and as soon as possible.
