We can look into that. The grain list is pretty long, and we like to keep it condensed.
What you can also do, which is much more flexible is to add a custom inventory fermentable to your account:
Under the inventory section, add a custom fermentable to your inventory. Set it mashed = false since it is sugar. Then it will appear in the drop down at the top of the list. The PPG and Lovibond values will be available at the manufacturer's website.
