Also take a look at this guide if you are requesting builders for a server/project.
Please note, if I deny a suggestion because it is already possible, then I mean it is already possible withing 10 command blocks (That do not spawn other command blocks) or up to 5 creations (Command blocks that spawn other command blocks) to make your suggestion.
If I critique your suggestion I am not hating on you. Learn the difference.
