Back up your minecraft worlds

Java minecraft has a feature where you can back up worlds and then on another computer you can see that world as long as you have the same account,  so how about we add that to bedrock edition! I have a world on my tablet where I have a lot of builds but I want to see those worlds on other devices like my computer (no changing your world files to external) and simply just press the edit world icon and by the delete world button is the back up button! Vote if you agree.
