Specify Filename(s) for CSV containing errors when loading Webform

What high-level problem are you trying to solve?
After adding/modifying a CSV file in ODK Central that has issues an error displays when trying to load an Enketo webform. The current error message states:

CSV column heading "" cannot be turned into a valid XML element

Here was a wild goose chase that ended with the realization that I was looking at the wrong CSV file.

Any ideas on how ODK could help you solve it?
Creating a more specific Error Dialogue when Enketo loads to indicate filename.CSV that is problematic instead of the current generic CSV error message. Something like:

filename.CSV column heading "" cannot be turned into a valid XML element

I'm not sure how to best handle multiple problematic CSVs, but including all of them would probably be helpful if that isn't too difficult. They could be joined with a separator like: "problem1.csv, problem2.csv, etc."

Upload any helpful links, sketches, and videos.
