reset any dimension (nether-END)

It would be good if Minecraft had the option either visible from the world or from the files to be able to reset our dimensions, it is annoying that in our world we have to go further and further to enjoy the new things that add to the game, I don't know if that is so complicated but it would be good if you could choose which chunks of your world you would like to reset, and we would be responsible for anything that happens to the world.
