Warhammer 40k: Rogue Trader Ship Character Sheet Question

I apologize if I have just missed something simple, but on the Rogue Trader character sheet, you can select "Character" or "Ship". On the "Ship" sheet, the ADD button does not add any additional lines to add more than one ship weapon. Any information that can point me in the correct direction would be tremendously appreciated! BONUS: I'd also like to be able to set up some macros for firing the ship's weapons, but haven't managed to figure it out well enough just yet.... a challenge for the braniacs?!?!? Thanks again, everyone!

I have made some headway with the following format: /em fires the ship's Hellus Macrocannons with [[(@{bs}+?{Modifier|0}-1d100)/10]] degree(s) of success! (Strength: 4} | Crit Rating: 4 | Range: 6) /em does [[(@{shipweapondamage})]] damage! This lets the NPC ship fire it's weapons at whatever "bs" skill I set for the crew and provides at least the first shell hit. I would REALLY like to figure out how I can get the damage roll to calculate based on the number of additional successes up to the strength of the weapon. If I come up with anything new, I'll post here for everyone to enjoy as they see fit!
