Exactly why I want to have an off/on switch for the A/C. On my other cars I never take it off of recirculation. Stuff from dust, pollen, road kill, smoke, exhaust etc would rather not smell...or I would run with the windows down.
Newer cars have cabin filters to handle dust, pollen, etc. Of course, ours do not have cabin filters lol. If you put ours in the straight up position, it closes it down. There's no air movement then, but this is what I do when passing a stinky *** farm truck hauling cattle and pigs, or if I pas through construction. You definitely don't want to leave it in that position when the car is parked. You want your car to breathe so the heat doesn't get sealed up in the cabin. Also, no air movement could cause mold to grow in the evap coil. I see what you are saying. We just have basic HVAC controls. I suppose you could come up with something to accomplish what you want. You could research HVAC controls from other Ford's around 99-04. Maybe there is a way you could add controls from one that gets you more control. Might be worth a look.
LOL, I use my AC maybe once or twice a year. I leave mine in vent/floor mode 99% of the time.
