Because the Ross Ice Shelf of Antarctica crossed the 180 degree meridian, there are currently two separate area in OSM for the ice shelf, as in https://www.openstreetmap.org/relation/2823691 and https://www.openstreetmap.org/relation/2823696 , and both of them are multipolygon because of islands and such within the area that are not part of the ice shelf.
Is there any method to group the two multipolygons together, so that when user search the term in any services depending on OSM, they can see the entire Ross Ice Shelf instead of two parts divided along the line?
