The code is kind of quirky in this respect, as what becomes line one's equipment after all is said and done is dependent on some arcane mix of relative numbers, and unit icons. I'm not sure of what the exact algorithm is, but it will shift around as you are monkeying with the build out of the unit.
Sure. But the first line won't change during the course of the game, only in the editor, and one can force the first line by use of F4/F5 and text editting, so long as you don't touch the unit again afterwards.
