Relative automation

Sometimes it’s hard to fit the mix in one turn. Automation is written down, but next day I realise that guitars need to be a bit louder. I know it’s not too complicated to select all the points and edit the value, but relative automation would be so cool! We would not enter specific values like “move from -12 dB to -10,5 dB”, but “move +1,5 dB”. Still able to adjust levels in the mix.
