Other than continuing to request recirc *on*, with a touch of your finger after engine start, I have know idea what you can do. Even after extended time in the recirc mode, it says the AC system will move that (recirc/outside air) door to a position to cause *some* outside air to enter, an mix with the existing recirc air. So at some given time your preventive smell-o-door, is going to crack open due to a command from the HVAC. I suppose there could be a way to re-program the HVAC to do what you want, but I would doubt it for safety reasons alone.
Maybe some vendor sells a cabin filter element saturated with carbon or charcoal or whatever that product is that can alter or cancel the odor.
