What does APX have to do with TX or the readout? This is a Receive feature whereby it PEAKS a particular freq. in CW mode. The Shift number should read out JUST as it does now.. It would only effect the position of the APF location as you move it. This is my understanding.
Wayne, Although that sounds like a cleaver idea, sometimes you want to keep the shift off freq. from your center pitch, but still peak someone in. This can help reduce noise that is in your pitch Band pass, but alow you to de-tune the noise around it... This presents a problem for your idea. It means that there would have to be a separate knob for the Shift and the APF location. Or at least this is how it should be.
