I don't know if this will help you but what I will sometimes do is to use an unused entry block in the expanded dough calculating tool for an item that is not in the list. For example, if I want to add malt powder and dried buttermilk to a dough formulation, neither of which is among the items listed in the expanded dough calculating tool, I will use, say, the barley malt syrup and fresh buttermilk blocks as proxies. Doing that will give the weights of the malt powder and dried buttermilk correctly, but the volume numbers will not be correct. So, I just delete the volume measurements in the final presentation or else I calculate the weight-to-volume conversions for those ingredients and then use those volume numbers. Usually, I correct the text of the output presentation to reflect the added ingredients.
