Product/Item Time Field to be used when building out item groups so that total labor time is consistent. For example, from the item/product catalog add a field so I can setup amount of time to install product/item, and then as items are selected, or utilized to buildout item groups, estimates ect. somewhere near the bottom a total of time could be populated only visible to me, not customers, this time could be easily converted to populate labor hours to complete a total job cost, item group cost etc.
