I don't believe I'm clear on how the import date formatting works.
I have a spreadsheet which contains dates in YYYYMMDD format, e.g. 20190102. To access the formatting options, I saved the spreadsheet as a CSV file.
When I load this file for import, I exercise the formatting options and select the YYYYMMDD format. However, the application still does not recognize the data as a date format, because my date elements in the model are not listed in the dropdown.
