Cutomize Inventory Columns

I have both leaf and pellet forms of hops, and liquid and dry versions of some yeasts.  But, I can't tell which is which in my inventory because I can't add any columns. 

I just started using BeerSmith, still on second day of trial but will almost certainly be purchasing.

Similarly to the original poster I noticed the hops form doesn't show up. For me it was in the shopping list. I prefer leaf or pellet depending on the use and amount. It would be nice if it showed up in the shopping list with form/type listed so I don't have to remember what I had intended.
