I need a way to assign an existing sample as an aliquot. At the moment it's only possible to generate aliquots of exisiting sample by temporarily deleting them and import again as an aliquot. Using the colums "ALIQUOT" and "ID" with the Update function has no effect. Would be a big improvement if the Update-function would change the properties of a sample to be an aliquot. I have 500 000+ samples to be changed though...
