This utility terminal program will generate clone commands in a specified range for each block, so you can copy-paste it into your server terminal and don't have to write it manually.

I did not find any other suitable command as a solution, so I just came up programming this small but powerful tool. I wanted to build with bubble columns an invisible elevator and however /fill didn't allow me to do what I wanted to do actually. So I came up doing it with dispensers and glass blocks (you can use any block, glass is just nicer in my opinion; so water doesn't flows in mass all around the world). Since /fill didn't allow (atleast on Bedrock Edition) good ways to add NBT I couldn't even fill the dispenser with buckets already, thats why the clone command came pretty handy.

My intention is to share it and help fellow people who are in the same situation as me and need something like this. I hope you like it and it's useful for you. I didn't implement any GUI since this would be overkill for such a small tool.
