Display blocks tag

[CAMMX9]

so what if display blocks had a tag called "Is Server" where when its on it makes the SERVER tell the player "Hey there's a block at [8367, 50, 2857]" so the player cant update it, but since the server itself has to tell the client it will use alot of CPU. oh yeah btw maybe you could add a "IF PLAYER" for seeing if the client has a display block/normal block at a position, if its possible.
