[Request] Save spawn points coordinates

Hi, can someone make a datapack that logs / saves spawn points to a file? (Spawn point is set when you click on a bed)
Would be useful when writing down base / home / cool location coordinates so instead of manually writing them you'd have a list already generated for you. Or for example when you have many bases and you want to have all their coordinates, then this datapack should do the work for you. I hope you understand my vision, if not I can elaborate. If you have a better idea that accomplishes the same goal, go ahead!

Thanks!
