Currently there is a VAS button when you go into the order details but it is not something you can use till after you ship the order. From there you then need to leave the shipping page, go to all orders, call up the order, go into the details bill the VAS then go back to the shipping screen.

Would be useful if there was an easier way to bill VAS on an active order. possibly a link listed in the green actions button. This would allow someone to bill the VAS right when they do it prior to shipping the order and needing to remember to go in and bill it.
