Update /fill and /clone

Currently on Java Minecraft, the /fill and /clone command are in a perfect state, excellent for building big scale projects, but on Bedrock Minecraft, the commands are lacking a major functionality. On Java Minecraft you can hit “TAB” and it automatically fills in the cords, this is the way it should be on bedrock but it isnt, on Bedrock Minecraft, if you hit tab it adds in the place holders ( ~ ) without the cords, meaning that you have to take a picture of the cords you want, and then type them in, which is a pain, This is why I think they should update the /fill and /clone commands to meet the Java Minecraft standards
