I mean such a function by which the white trace becomes flat (0dB - reference line) so the yellow trace will be displayed in relative to the white one. This is because noise generators will not give out uniform output from 1kHz to 2GHz, and also we don't need absolute dBm readings when it comes to measuring filters.

Understood, thank you.
I did have some thoughts in that direction when the original analyser but were dropped for various reasons. What I had considered was adding a trace-maths function so that the difference between two traces could be plotted with it's own scaling. I think that would do what you are asking without the need for a normalisation or calibration run. I think it would be a useful feature, and something worth considering - No promises that it will make it into V1.0 though.
