OpenAtlas

@Bernhard Koschiček-Krombholz thanks very much for the new import feature #2244, it works like a charm and is really helpful.
Sometimes we need to import features, finds or strat. units, bones or in general subunits into already existing OpenAtlas Superunits. Would that be possible with the existing framework already or could we think of something like another column in the import csv e.g. "OpenAtlas Parent ID" that then points to the already existing parent?

Thanks in advance!
