At this time, there isn't the option to automatically add interest/late fees to invoices. However, you can manually add service fees to invoices. Here is a helpful guide for your reference. I can see how being able to automatically add lates fees to invoices would be beneficial for you. I recommend leaving feedback by heading to the Gear icon and selecting the Feedback option.
