I would like to personalize a little more the POS Qweb Report_receipt.

Actually I've already modified it for my need and even if not perfect works fine for my restaurant. But I need an expert advice to see if I can add a separation line based on the internal code displayed. 

See the picture here:

(sorry I don't have enough karma to add picture or a embedded link)

Is possible to check the code before and eventually add a graphic line if necessary? Will be very useful to separate special orders and avoid confusion in the kitchen.
