reductant quality test

any chance we can have this option added to the DVT controls for the newer duramaxs with the DEF?

having an issue with one derated down to 4 mph and saying DEF quality low. fluid was replaced. tank washed, sensors cleaned and verified to be working. nozzle cleaned and working, etc but no way to get it to check the quality again without towing it to the dealership or driving a bunch at 4 mph. not going to happen. there are options for doing service regens, testing DEF pump, leaking nozzle, reset Nox sensor, etc but not for DEF quality

is it possible to add this feature that the Tech 2 and some other scanners have to the DVT controls?
