This question seems like it must've been asked already, but I can't find it.
In Illustrator CS4, imagine I have 16 artboards, each with a GroupItem/PathItem placed on them. None of them are aligned. I would like to select all objects, and then align each object relative to it's respective artboard. Like - align to artboard, but each one is getting aligned to a different artboard.
Short of writing a script, I can't see a way to do this, but it seems like a thing that Adobe would've included this.
