As I see it SA doesn't have this - just btw...
I now also would like to rant about something else which I always detested. Could you tidy up the T2 Constructor buildlists? Those have a more or less random structure at many points. Overall there is some sorting but here and there some buildings just pop-in and ruin it...
With that said make the list just like the T1 list i.e. keep the same sorting you set up: Energy -> Storage -> Metal -> Labs -> Radars'n'Stuff -> DT/Fortification -> Turrets (starting with "skirmishers" then LR Plasma and then AA) -> Special Stuff (that would be BB, Nuke and similar on T2). Currently you have the gantry on the 2nd postion (for K-Bots) and the rest of em at the very end. After that the ressource buildings and radars are fine but after the fortification there suddenly pop up things like the helipads or the seismic detector (the Core version might want to have a buildpics of its own btw - the Arm buildpic with it's vivid green also ruins the cold Core atmosphere

). Apart from small details (like the LR Plasmas being put in too early and the mentioned labs at the very end) the rest of the buildlist then is somewhat nice although for Arm there suddenly are some Decoy Fusions popping up at the end...
