I am just curious if there is a way to either auto-make an array with a bunch of selected objects all at once or drag and drop multiple objects into an array at once. I noticed you can add 1 at a time by dragging the object onto the inspector array name, but if you try to shift click or control click multiple ones it automatically deselects the inspector item making it impossible to drag anything onto it.
When you have the Gameobject with the array selected, click on the lock button in the inspector as shown here: Unity How to : Drag multiple objects to array - YouTube
