Post gain adjustment

Hi MediaServer community!

Many many many thanks for keeping this platform alive. I have been a SlimDevices fan for many years (these things are virtually indistructible - especially the Squeezebox III - aka Classic! - I still have in my collection a working SlimDevices SBIII White!)

I have a request - I am not sure if this is possible or worth the effort:

When using Replay Gain (I LOVE SMART GAIN) the overall gain is attenuated to by approx 7 or 8 db - would it be possible to have a post gain for ALL streams to lift this up again? This makes it source consistent on a multi-source amplifier.

My current player settings:
SmartGain: on
Gain on remote streams: -8
Spotty replay gain: off
Don't stop the music: on
ASK
Post gain: +8 (+/-n - n=-x - .. +x)

Thank you
