Sequencer Visibility with thousands of Actors

Hey folks,
is there any best practice to manage large amounts of actors and keyframe their visibility? I have thousands of actors but i cant activate the Visibility/ Hidden in game property for every actor each. This would cost me too much time. Is there any way to copy/ paste this property? The only solution i found is to make a ton of streaming levels but this coulnt be the best solution. Is there any better way?

In 4.22, you’ll be able to bind multiple actors to one track. That should make your workflow easier.

Thank you this is a Timesaver!
