Adjust volume of individual songs?

[eloquent]

I was going to ask about the Volume Normalizer feature, because I haven't noticed it working in dAP. But I just found out it's part of the optional Power Pack.

Is there a way to adjust volume of songs in a playlist and save the adjustment, so they will always play back at that volume?
I have all sorts of songs in my playlists, both rock and classical, and the classical ones need to be played at a much higher volume, and the volumes of the rock numbers also vary a lot. And I don't like jumping up all the time to adjust the volume!

Thanks for any suggestions.

The volume adjusting bit should work in dAP - it should be set on the green 'A' for auto, the first time the file is played the volume is calculated and set for next time, alternatively you can manually set it.
