Stucture Block can't Upload

The Summary tittle says everything,

 

thanks for the new update, and i have a suggestion "please make the structure block of minecraft bedrock like the one on java, that can be save and load on local worlds please, or you can just add a comman that can copy and paste blocks please, and the auto completion when pressing tab in windows 10 then it will set the coordinates of the cursor to the command. please and thank you"
