Fix block copy mode in Minecraft bedrock

They should make the copy block mode for Minecraft bedrock edition, like the one for Java edition,

 

For example when you put diamond blocks in a chest in Minecraft Java and copy it, and you put it somewhere else, the chest still has its stuff inside but in Minecraft bedrock if you copy a chest that has diamonds inside and you put it somewhere else it doesn't have the diamond blocks inside please fix that.
