i wish we had like /ally or /friend so i dont have to /cmodify EVERY chest and door i own and when we claim land i havent tried but i think it will make only one of us be able to break and place blocks so i think some command like that to /cmodify everything to the player

Place pstones. Add friend to stones with /ps add. Unlock chests and doors, and/or set to public access.

Alternatively, you are aware /cmodify followed by /cpersist will allow you to modify all locks you click until you type /cpersist again to toggle it off?
