U.S. Variety Hops not in Beersmith

I got several new hops from hops direct (Hallertau US, Magnum US, and Tettnanger US) and I wanted to add the inventory to beersmith
but the U.S. Varieties are not in the program. I usually add my inventory by adding the weight, and change the Alpha Acids to reflect the crop I got.
Any Suggestions?

Go into BrewSmith's Help then open/search for Adding Custom Ingredients → Hops.  You might also want to look at the add-ons (Under File → Add-Ons...) because there might be something for US Hops but I'm not positive without looking.  Anyway, I think what your after is the adding ingredients which can then be selected within your inventory...  I hope this helps.
