i have addressed this question in response to a discussion question, but wanted to throw this out there for others as well. I would love to see an "Apply to animal group" button in the trac side. we manage our groups of hogs in trac (stock was not really geared right for how we do hogs). Now I have to allocate inputs to "feed" the group, but this does not account for the cost of my machinery/labor to the group. By having the "Apply to aninmal group" button I can pull out a feed supply, the equipment/person much in the same way that I would "farm" a field.
