If you want this feature applied to ALL clients with LEDES, you will enable this functionality from the Firm Setup/Invoice Presentation tab.
If you want to apply this to a specific client, it's a bit trickier.
Head to Billing/Ready to Bill. Find a client that you want to enable this functionality. Hover the mouse over the client/matter. A Lighting Bolt/Left Arrow will appear on the right side of the matter. Chose the Right Arrow.
From the next screen, use the checkboxes to include the elements needed on the invoice.
In the following screen, click the Configure Formatting button in the upper right corner. You will then see additional formatting options that can be applied to this specific client. Make sure you save the settings before leaving. (see image 3)
