Is there a way to download all of the Mosaic files as one single file instead of individual unlabeled .csv files?
I do not see any indication that it is possible to download a single version of the MOSAIC files on the Data Downloads page, though the script at the top of the Data Downloads page should help with the labeling, and the consistent layout should make it fairly easy to combine multiple files. Because each file has a unique provenance and citation, I assume that keeping them as separate downloads aids in correctly attributing the data to those who worked to create it (though I understand how needing to knit these together is additional work on the user-end).
