Lower all fader levels, keeping relative positions

Is there any way to lower all fader levels (or even just selected tracks) by a specific amount, say 6db, while keeping all relative fader positions? Thanks for your help.

select the track you want to lower.

select ‘q-link’ at top of the mix console’

lower faders…

Cool thanks. I was more wondering if there was a way to, say, type in a specific amount of decibel reduction that could be applied to all selected tracks. But I’ll go with this way for now.
