Is it possible to set this up so that you can point it to a remote URL to fetch the CSV? For example, I'd love it if I could point it towards a Yahoo! Finance API call that returns a CSV file and have my dashboard auto-update. Or Dropbox URL. Or any remote URL. That would be awesome.
That exact use case is not currently possible, but it's something we've talked a bit about. We're still considering doing something like it in the future.
