Yes, adding a switch to the robot or the driver's station is easy enough but it is also easy to forget to set the switch in the heat of the competition and then your tracking is worse than useless. If you put the switch on the robot you lose the ability to correct is for the whole match. If lyou put it on the driver's station, then the information doesn't get to the robot during autonomous mode. Hopefully, the new field management system will allow driver station inputs during disabled mode.

That is why I'd like to use the built in alliance function.
