Borders?

So in my game, the footprint of the levels are huge. 500x500. And I’ve noticed a problem. I can’t count to 500 for every block I place. So, what if we had borders that could be activated from the camera feature that will activate the borders of the area that the camera follows you? Because there is no way that I can fit the whole level into a 500x500 space without making a few mistakes. Can we have this added?

If you need clarification, please just ask me.
