Stockpile Managment for Production Stations

The automated stockpile management is frustrating. The station can’t work because there is no engine available at the station or just 3 of 4 brakes, while there are 9 wheels in stock.
Would it be possible to set a maximum of 1.5 times (rounded up) the needed amount for parts, so there are max 6 wheels, 2 engines, 6 brakes, 3 seats, etc… ?
I would really appretiate that.
