Good luck with that. My company pulls the same crap. Talked to them about it. They didn't care.
This is a perennial problem in engineering (and also in a number of other fields). The sad thing is it really rewards people for maintaining their mobility and changing companies periodically. Sometimes you can work the system in such a way that you can run the evidence past your manager and they can get the raise for you, but it's just honestly hard to keep up with the pace of pay in the industry by staying with the same company unless you go after a rapid promotion track.
