Using reverb effects

I have several vocal channels recorded and want to apply the same reverb on
all channels at the same time. So far, when I select all the vocal channels and drag the reverb effect
over the channels, they have a effects icon on each track, but I have to open each track individually to set the needed reverb.

Make a bus in Fairlight, insert a reverb on the bus channel, and use bus sends from the channels you need reverb on.

The usual way is to use an Aux bus for the reverb and adjust the send level from each track. This means only one instance of the reverb effect.
