You would have to send a request to BG support and be very specific about what you would like added. If you can, attach a drawing or image or provide a link to one somewhere on a website, they might respond to your request.
Some of us would not mind if they took that feature out of the Military section and gave it over to a "Symbols/Emblems" section which would also include various fraternal/organizational emblems, often found on stones.
