Is there a delta transform for collection? I made this guy here, he is made of 29 individual objects, I want to draw over it with grease pencil, but I cant rotate him with the rest of the frames. Its nice that I can use the delta transform to change the puppet size to make a variety of siluets without animate them once more but that's useless if I cant move them around.
RIGHT-CLICK your collection in the outliner, Select Objects
Now you can move, rotate, scale, etc. all the objects together.
Or:
If all the objects you want to move together are the only ones visible, hit A to select all and move, rotate, scale, etc.
