How to root several tracks

How to root several tracks into one group please ? is there a way or should i manually root them one by one ?
Thanks a lot,

yeah, create your group, select all tracks to be re routed and hold the shift modifier key while assigning the output. or try shift+alt (not sure if you’re on a pc or mac, one of these should work).

while in mixconsole, you can do this without creating a group beforehand; just select the respective tracks, right click and choose to create a group for selected tracks. it will create the group and route the selected tracks at the same time. (in true steinberg spirit, the second method is only accessible via the mixconsole, not from the arrange.)
