Sort list into another List.Setintersection or replace multiple items into list

Hi, Hope this makes sense. But I want to try get the ElevationMarker list sorted into the list above where its based. How the List.Setintersection is sorted but with the ElevationMarker views in it. I need the list structure for later on

sorry for all the lines… I think its something like this but not quite right!

closer but not quite right, Its just pulling one element from the list :laughing:
