Given that companies such as Silca now have accurate and relatively affordable digital pumps and repeatability and testing are important, has anyone ever tried putting something such as electronically controlled blow-off valve in line after the gauge?

The idea being you set an exact pressure on the pump and when the pressure reaches the desired level, the blow-off then dumps the pressure so you know you have reached the exact set level.

Bonus points if someone can battery operate it and make it universal and app controlled like the display on the tacttico so you could use it in line with any air source, whether pump or compressor supplied.

Seems like it would make something like inflation for a cycling team incredibly more accurate and efficient. Have a compressor, the controlled blow-off valve and a list of F/R pressures for each rider for the day and the mechanic just inputs the number, hits the air and the tire is perfectly inflated each and every time.
