Is it possible to deactivate items faster than normal? im trying to deactivate all my items, theres more than 30 of them i think

I ran into the problem several times, Just tick all the items then deactivate all in one go

Yea, there's no special way to deactivate them all in one click, you need to go item by item, I guess.
Though you can check the items and transfer them to a set, I think that would deactivate them.
