User blog comment:LOTRMod/Joetater: A Region Saver/@comment-26172435-20160826224537/@comment-25612015-20160828125241

Come to think of it, for the mod used to indicate region files to transfer, a simple /markregion command will do to add the region file where the player stand in a list.

The four marker blocks thing would be needed only in order to mark the precise chunks to save, with another tool used to create a region file with only these chunks inside.

In every cases the region/chunks borders smoothener would be needed.
