Is there a way to set a CDM1250 so the volume of the keypad tones increases as the audio volume increases?

I don't really like the fact that in a high-noise environment, I can't hear the tones, even though the received audio is quite loud.

The "Tones" menu has an option to turn the keypad tones on or off, but I don't find anything regarding volume adjustment.

Thanks.
