Feature Request - trainer self calibration

There is an option of Virtual Power, and this is fine for many of us, who don’t have power meter or smart trainer. But what, if I have (or borrow for a moment) powermeter and many bikes and trainers? Can software give me an opportunity to make my own profiles of indoor trainer and bike? It should be possible to implement just by creating few measurments of 10 maybe speed values and estimating power curve. It will be more precise, than build in Virtual Power.
