Custom Shape Management for Reinforcement (NYSDOT)

NYSDOT Bar List.pdf

I need to add custom reinforcement shapes to my model so they can be recognized in my bar schedule. I am currently running ACI (Imperial) Code but I need add additional rebar shapes for NYSDOT (see attached). How do I add these additional rebar shapes to a custom .RSF library? As you can see NYSDOT uses additional shapes on top of ACI's. I need to add N1-N23.
