Better order in the selected units buttons?

I think that it should be easier to select units in the buttons of selected units if every unit had a box assigned, or a place to find it quicker. For example, bots in the first line, vehicles in the second line and airplanes in a third line or columns. When I am in battle sometimes I get crazy trying to find the group of units I want to select in the panel of selected units, and the pop up menus dont help.

it couldn't be hard to make a mod that did that
