Add selected actors from world outliner into an array

In UDK (Unreal Engine 3) you could select all the actors from the world outliner and populate an array instantly by clicking an arrow that said something like “use selected objects in content browser” but it seems like in ue4 you need to populate them one by one unless I’m missing something?

I’ve tried dragging and dropping but nothing works is the workflow to just drag one by one and hope u don’t miss one or re-add the same one?
