To assist in rapid iterations for greyboxing, I constructed a simple system (based on your code) that aligns sublevels added to a persistent level (added via levels panel). It is near exactly what I was hoping for and is a MASSIVE time-saver over my old method. I’m also very happy to know that I also have a solid framework for when I get to the next step.
You’re a hero. Thanks again - this is all extremely helpful!!!
