Thanks so much everyone for your responses!
I took a look at 99Instances2Go 's and plinkie 's capxs. I figured, I'd just add the "rotate to" action to my project, because that looks like the easiest and shortest version to me (I'm a lazy person). Thanks — for your suggestion!
This is solved, thanks again!
(I hope I don't disappoint those who created a capx, I opened them and read through it, I just think that it's less work to just optimize my existing project. Thank you anyways for taking the time to deal with my problem. :) I wish there was a thanks button on this forum...)
