I am not sure I understand what you mean by "track by another metric". Can you explain a bit more and I will see if I can help?
A thought, as an extra column would be great for my team (we are university students doing a group project), but instead of adding other column to crowded space, how about changing one column to be adjustable?
For example the column that consider the cost of stuff is useless to us and is removed. So, making that adjustable to suit specific purpose as desired would be great :)
