[FR] Add the option to change Volume Automation Lane range

Right now the automation line for volume shows from -199.99dB to +12dB If I have a mixing project with lots of +/-1.XdB automation when I try to see an overview of the hole project is almost impossible to see when a automation line change +1dB and when 1.5dB (or even more).

If that can be changed to for example -12dB to 12dB (or whatever the mixing enginner needs) a +1 dB should be easy to see without change the track size to full window.
