de-bittered Black malt

So the latest issue of Zymurgy has a recipe for Baltic Porter which calls for 8 oz. of de-bittered black malt.  I dont see this on the list of available malts in Beersmith 2.  Is there a malt I can substitute and have the recipe come out OK, or does this go by another name, or can I add it to the list - if so, how?  Thanks,

Steve

Beersmith has a short, 2 minute or so video on how to get this done here,http://beersmith.com/video/?utm_source=getresponse&utm_medium=email&utm_campaign=beersmith_blog&utm_content=%5bBSHB%5d%20%7b%7bCONTACT%20"subscriber_first_name"%7d%7d%2c%20S

Thank you!  Got 'er done
