Feature request - align for every unit, not just SPL

[Ratterbass]

And the last request (for some time )

Being able to align the dataset for every unit not just SPL would be nice. Many people use REW not just for room measurement but also for measurement of electronics, where the SPL graph is not of relevace. To easily compare frequency responses of different DUT or at different levels it would be nice to be able to align for every unit and not just SPL.

Thanks!
