The feature you refer to is termed ONE TOUCH, don't know when they came out but they were on my MK1 mondeo(1995), but only on the drivers window on these.
They are so easy to add, have got them on all four windows on my cossie sapph, they are not even expensive new, you cand even add them to the lecky sunroof or the UP motion as well as the down motion of the windows.
Only FOUR wires to do, live earth and then the two wires to the widow switch after you have cut into the wire that goes LIVE when doing what you pressed, orientation is needed but easy.
