Show/hide group of actors

I know there is a block for show/hide specific actor, but how about several actors at once?

For example I have a dialog box with ok button in front of it. When I press ok button both the dialox box and the ok button actors disappear.

You could just create a new group and put all the actors you want to show/hide into it. Then you can just loop through the group:

Thank you. I thought there was a block for this. I will surely make it work like this.
