If you use the "Upload Data" button on the Astra console to initiate a CSV upload, it's pretty cool, but it it seems like the dialog is insufficient. The ORDER of columns matters when defining keys, but the dialog that one gets after the file has been initially parsed doesn't allow one to control the order of the columns in the partitioning key (which I guess doesn't matter) or the clustering columns (which does matter). Am I missing the way one can reorder columns in this interface?
