Can you add the option where the schematic stays loaded on a world, or it always shows where you originally stood to load the schematic?

I was going to suggest this feature myself.

However, I'd suggest a "Save Coords" and if "Saved" you the "Load Coords" will be enabled.

The coords can be saved in a JSON format:

{
	"schematic":"example.schematic",
	"x":"100",
	"y":"100",
	"z":"100"
}

This was supposed to be solved by session states, but sadly I never got around to finish the feature.
