With the newer method for managing calculations, we are able to associate multiple Products & Services items to the same calculation. We can see all of the items that could be related to each calculation(based on matching UoM) by using the (+ Product) search under each calculation, but there isn't a quick way to make sure that all UoM's have a calculation. A section, option, or field that displayed all the UoM's that exist on visible products, but that are not yet on a calculation, would be helpful to make sure we have everything accounted for.
