Fast way to assign a new/unique number to all tiles on a canvas?
Just bought PE, and have been using it all day. I've created a set of 24 tiles, and have arranged them on a 20x20 tile canvas. Is there anyway to now assign every tile on the canvas a new unique number (ie. number them 1-400)?
I feel like this would be less tedious than duplicating tiles every time I want to make some minor tweaks to the tiles on one part of the canvas. I'm new to this, so please forgive my newbiness if there's a really simple solution to this.
