World Editor Command Block and wand

The world editor has been done many ways through java, but can't fully be accessed with Bedrock, yet. 

With varieties of unique blocks out there such as the command and structure blocks, surely there is room for another; perhaps for world edit. It can be quite simple. 

All it needs is the wand or some other tool to start and the 'world editor' block for editing. And in the block, you can choose what block you use with the wand.

Also any shapes or designs to choose from such as a sphere or a straight line to make objects and buildings. You should be able to click one corner and move to another end and click to fill in entire area you have selected as long as the limit allows.

Next, the copy and paste feature. simply click the two farthest corners from each other to instantly copy. Now for pasting, click where you want your item to go. This is where it gets tricky. I think using the last clicked location from the copy would make it easier to know where your item goes, unless there is coordinates provided.

Finally, A setting to mirror, reverse, or even flip your item upside down with a few switches.

This is just a few ideas, but with just a wand and a 'world editor' command block, world editing will be so much faster and improve the game's quality of life. Wouldn't it be great to have a 'world edit' officially on Minecraft to speed build those maps? Best of all, NO MODS!
