Hi Molly, Here are some more screen shots. It seems that in this scenario, only the source assigned to the "TestSourceId" name will be imported to the SampleID, even when multiple source options have been assigned as options for the Sample Type. Because we would have multiple projects collecting PBMCs we need a way to get the Patient and Visit identifiers from multiple projects ported over to the Sample Name that will be assigned to the barcodes for each specimen
