Setting a default gain for multiple scenes

I have a show with 60+ scenes where appropriate gain levels for multiple actors were not defined when making the scenes

So now i have the problem that i need to set a gain level that is correct for the whole show. Could i do this by updating and adjust the gain there for all scenes?

Can be done very easy with the update function under scenes.
Refer to the manual for details…

If you need to do it quickly, you can also switch the preamps to Recall Safe.
Then the preamps are not recalled by scenes.
