Right now neither the filename and the file-content really saves information that gives you an understanding of which card and which filters were chosen when the data from the card was collected.
If either the filename contained information, or if a header row in the csv, or extra sheet in a xlsx file, this would make it a lot easier to collect data and help prevent any missunderstandings of what was shared with other colleagues in ones organization once a file has changed hands a couple of times.
